WLM GC coordinates

Hi there, I see you are the editor who added the ra,dec coordinates for the WLM globular cluster. Do you have the source for these values? Because according to SIMBAD those are the coordinates of the LEDA 910901 galaxy, and these are the WLM-GC coordinates. Regards Gaba ^(talk):H 22:32, 14 January 2019 (UTC:T

That was just an estimation I did based on the image of the cluster in Pan-STARRS since I couldn't at the time find a more precise estimation of that. Definitely use that simbad listing over mine, it's probably more accurate as well. exoplanetaryscience (talk) 23:22, 14 January 2019 (UTC)

List of earthquakes in 2019

Hi Exoplanetaryscience. I've looked at the edit history of List of earthquakes in 2019 and see that you have twice inserted details about the Maryland quake and twice had the details removed with the rationale that the quake was of low intensity and had low impact. This experience falls under the essay Wikipedia:BOLD, revert, discuss cycle, which people call BRD. You were BOLD in inserting the details, then you were REVERTed, now you need to DISCUSS the matter on the article talkpage and see if you can get consensus for using your material. If you cannot get consensus, then you can accept that you have tried your best, and simply move on to doing something else. You may wish to get further clarity by alerting (in a neutral manner) users at Wikipedia:WikiProject Earthquakes of the discussion. I hope this helps. Ping me if you need further help.

DYK for Kamchatka meteor

On 22 June 2019, Did you know was updated with a fact from the article Kamchatka meteor, which you recently created, substantially expanded, or brought to good article status. The fact was ... that in 2018, an asteroid measuring 12 meters (39 feet) across air bursted over the Bering Sea near the Kamchatka Peninsula with the force of 173 kilotons of TNT? The nomination discussion and review may be seen at Template:Did you know nominations/Kamchatka meteor. You are welcome to check how many page hits the article got while on the front page (here's how, Kamchatka meteor), and it may be added to the statistics page if the total is over 5,000. Finally, if you know of an interesting fact from another recently created article, then please feel free to suggest it on the Did you know talk page.

Doublet earthquake?

Was the USGS link originally messed up or something? Curious as to what could have happened here (2019 Ridgecrest earthquakes). Master of Time (talk) 19:50, 4 July 2019 (UTC)

Not entirely sure, being quick to respond to things isn't exactly my strong point. All I know is that very early on the earthquake was listed as a 6.6, and then within a few minutes downgraded to a 6.4, but then I noticed that every other time I went to the USGS page for reference the quake info changed. Then two different earthquakes showed up and that was my main source on it being a doublet, backed up by my calculations that two 6.4 earthquakes would appear to mimic a single 6.6 earthquake in intensity. exoplanetaryscience (talk) 20:03, 4 July 2019 (UTC)

New article for recently discovered asteroid.

I started an article on 2019 LF6, which is believed to have the smallest semi-major axis of the asteroids known. This beats a record set earlier this year with 2019 AQ3, so an update is in order. ― Дрейгорич / Dreigorich Talk 12:28, 9 July 2019 (UTC)

Well damn! I should really keep better track of these new asteroid discoveries. Makes me wonder what else I've managed to miss. exoplanetaryscience (talk) 19:07, 9 July 2019 (UTC)

T Tauri

Hi i’m confused by the following, which has been in the article since 2007.(It wasn’t written by you). It may make perfect sense to someone more knowledgeable than me: “A protostar is the denser parts of a cloud core, typically with a mass around 10⁴ solar masses in the form of gas and dust, that collapses under its own weight/gravity, and continues to attract matter.

The protostar, at first, only has about 1% of its final mass.”

Does this mean the inner core of the cloud, a cloud which has a mass of 10^4 suns, has a mass in the range of 10^-2 suns? Or does it mean something else, or is there a typo? ThanksRich (talk) 05:30, 21 August 2019 (UTC)

The phrasing is very vague so I'm not entirely sure, but it might refer to very early on the star's history where obviously it would have to pass 0.01 solar masses at some point- or it could refer to later when it could reasonably reach 10 solar masses in the inner region. Honestly the answer is open to interpretation and could probably do with a needs clarification or dubious tag. exoplanetaryscience (talk) 16:49, 21 August 2019 (UTC)

Thanks for updating.

Thanks for getting the info on these new moons. Unfortunately I have not been able to determine what their names or what their orbits are, so thanks for trying to get this info for me + the articles on the new moons. ― Дрейгорич / Dreigorich Talk 20:58, 7 October 2019 (UTC)

No problem, all the moon orbit info is being disseminated by the MPC if you're interested in seeing for yourself: [1] as well as already provided here: [2] exoplanetaryscience (talk)

Thanks. I've updated the Saturn template to add in the new moons for you. ― Дрейгорич / Dreigorich Talk 21:14, 7 October 2019 (UTC)

Thank you so much for the updates! Double sharp (talk) 06:33, 8 October 2019 (UTC)

Discrepancy.

There are 82 moons of Saturn, but the table only lists 73. As an emergency measure to avoid confusion, I have mentioned that nine moons are yet to be announced so that readers do not get confused. ― Дрейгорич / Dreigorich Talk 21:21, 7 October 2019 (UTC)

Sounds good, I plan on adding the extra moons in based on Sheppard's elements if they don't get MPEC'd soon, for what it's worth. exoplanetaryscience (talk) 21:24, 7 October 2019 (UTC)

Wait, wait, wait.

I think S/2004 S 29 was assigned wrong. It belongs to the Inuit group. And S/2004 S 24 should be a Gallic moon. A very, very distant Gallic moon, but its inclination matches the others. ― Дрейгорич / Dreigorich Talk 21:34, 7 October 2019 (UTC)

Oh, you're right. It is an Inuit moon. But S/2004 S 24 I don't think should be classified as a Gallic moon unless we can get some confident source that something that far out still belongs to the same group. exoplanetaryscience (talk) 21:40, 7 October 2019 (UTC)

The Gallic group might be more spread out than we thought. This might turn out be another loose Pasiphae group. ― Дрейгорич / Dreigorich Talk 21:43, 7 October 2019 (UTC)

I’ll do a check when I’m available again for if their node correlates or not. If they all have such similar inclinations, it ostensibly should. exoplanetaryscience (talk) 22:02, 7 October 2019 (UTC)

@Dreigorich: Here are the inclinations and notes of known gallic group members, compared to S/2004 S 24:

Moon	Inclination (°)	Longitude of the ascending node (°) (/360)
Tarvos	34.679	94.514 (0.263)
S/2004 S 24	35.538	333.879 (0.927)
Albiorix	38.042	107.272 (0.298)
Erriapus	38.109	141.949 (0.394)
Bebhionn	40.484	193.152 (0.537)

It seems pretty clear to me that S/2004 S 24 isn't associated with the group, as the node puts its orbital plane almost as different as possible from the orbital planes of the other moons, while still sharing a similar inclination. exoplanetaryscience (talk) 22:44, 7 October 2019 (UTC)

Interesting observation. It's facing the opposite direction. This makes its inclusion in the group even less likely. Though we don't really check the nodes for Jupiter's moons to assign dynamical families, so I'm not entirely convinced it's not part of the group. ― Дрейгорич / Dreigorich Talk 23:15, 7 October 2019 (UTC)

National Geographic says it might be Gallic. Sheppard has on his site: "The other newly found prograde moon has an inclination near 36 degrees, which is similar to the other known grouping of inner prograde moons around Saturn called the Gallic group. But this new moon, provisionally designated S/2004 S24, orbits much farther away from Saturn than any of the other prograde moons, indicating it might have been pulled outwards over time or might not be associated with the more inner grouping of prograde moons." FWIW, it seems that it will receive a Gallic name, regardless of whether or not it actually is in the Gallic group. Double sharp (talk) 20:58, 8 October 2019 (UTC)

Since the tidal effects of Saturn's rotation are basically negligible at this distance from it, you could consider their node difference just as significant as their inclination difference- it'd be the same energy difference if all of them had inclinations of ~35-40 degrees, and this one had an inclination of 70 degrees. And under that scenario, nobody would be advocating it being part of the group. exoplanetaryscience (talk) 21:44, 8 October 2019 (UTC)

In case it's not part of the Gallic group, it will be a weird case of "nomenclature inconsistency". Perhaps S/2004 S 24 is indeed part of a new group and then its name will be an outlier in its new group. Not to brag, but it's happened once around Saturn before. ― Дрейгорич / Dreigorich Talk 03:07, 9 October 2019 (UTC)

Some other groupings, for the Inuit group:

Inuit group

Moon	Inclination (°)	Longitude of the ascending node (°) (/360)
S/2004 S 29	45.102	140.675 (0.391)
Siarnaq	45.798	63.738 (0.177)
Paaliaq	46.151	352.043 (0.978)
S/2004 S 31	48.815	73.494 (0.204)
Kiviuq	49.087	352.000 (0.978)
Tarqeq	49.904	91.955 (0.255)
Ijiraq	50.212	151.270 (0.420)

They do seem clustered themselves, although not quite so strongly. Either way, the all 7 only cover a range of 44.2% of a circle. If you consider Kiviuq and Paaliaq to be their own group, then the remaining 5 only cover 24.3% of a circle.

Some other possibly younger groups I noticed while making a diagram of the orbits of the moons:

Hati group

Moon	Inclination (°)	Longitude of the ascending node (°) (/360)
S/2004 S 20	162.570	350.760 (0.974)
Fenrir	162.832	239.040 (0.664)
Jarnsaxa	162.861	21.097 (0.059)
S/2004 S 37	162.937	166.803 (0.463)
Hati	163.131	322.951 (0.897)
S/2004 S 12	164.042	313.621 (0.871)
S/2004 S 7	165.596	346.264 (0.962)
S/2004 S 34	166.039	311.750 (0.866)
Loge	166.539	343.990 (0.956)
S/2004 S 39	166.579	194.914 (0.541)
S/2004 S 17	166.881	19.994 (0.056)

Discounting Fenrir , S/2004 S 37, and S/2004 S 39, which have inconsistent nodes with the other 3 (as well as each other) despite having relatively similar inclinations, Jarnsaxa, Hati, S/2004 S 20, S/2004 S 12, S/2004 S 7, S/2004 S 34, Loge, and S/2004 S 17 have a node distribution of only 19.3% of a circle- an extremely unlikely proximity for 8 of 11 ostensibly randomly distributed moons with a similar inclination.

S/2004 S 35 (blue) & Phoebe (red) groups

Moon	Inclination (°)	Longitude of the ascending node (°) (/360)
S/2004 S 25	172.996	276.414 (0.768)
Phoebe	173.047	~270 (0.75)
Suttungr	174.321	252.712 (0.702)
Thrymr	174.524	246.531 (0.685)
S/2007 S 2	176.681	113.109 (0.314)
S/2004 S 35	176.717	332.737 (0.924)
S/2004 S 23	176.988	223.281 (0.620)
S/2007 S 3	177.22	96.946 (0.269)
S/2004 S 22	177.321	279.688 (0.777)

The Thrymr/Suttungr group has a node distribution of a paltry 15.7% of a circle, which is especially significant considering that the moons have inclinations of so close to un-inclined prograde, making large node differences actually fairly small in terms of angular difference. Then the group formed by S/2004 S 35, S/2007 S 2, and S/2007 S 3 has a node distribution of 39% of a circle, which might seem quite insignificant, but again with their very "low" inclination. The node difference is about as significant as if the satellites were mutually inclined by 2-3 degrees to each other (rather than the 0.5 degrees displayed here)

I know a lot of these look somewhat suspicious, and I agree. Probably a lot of them are just seeing patterns where they don't exist- but the Skathi group definitely exists, I'm 90% certain the Phoebe group exists, and I'd give 70% odds of the Hati and Aegir groups existing. Who knows about the Skoll & S/2004 S 35 groups. I'd have to do some long term orbital dynamics analysis. exoplanetaryscience (talk) 07:26, 12 October 2019 (UTC)

Interesting. However, the inclinations and eccentricities when plotted against each other show no obvious clustering for the Norse group as far as I know. They seem fairly uniformly distributed unless orbital data has been refined since I last checked in 2016 or so... Could you compare e vs. i for the retrogrades and see if any obvious clusters stand out now? ― Дрейгорич / Dreigorich Talk 14:02, 12 October 2019 (UTC)

It might be based on faulty info, but i don't think the eccentricity should come into play very much. While the gallic group has some relatively consistently high eccentricity (0.333-0.530), the inuit group has quite a wide range of eccentricities (0.1081-0.4401). In making the groups I did here, I tried to focus on objects that did have mostly intersecting orbits in terms of perichron/apochron, but as far as I can tell the exact eccentricity can be somewhat variable- and as almost every moon of Saturn has an e below 0.5, and many below 0.3, I don't think its exact value will come into play very much. exoplanetaryscience (talk) 22:00, 12 October 2019 (UTC)

You might be right. Maybe Saturn's groups play by different rules than Jupiter's groups, which are easily distinguished by e vs. i alone. ― Дрейгорич / Dreigorich Talk 22:32, 12 October 2019 (UTC)

Inclination

A few moons of Saturn sort incorrectly for inclination, and I can't figure out how to fix it. A few are also horribly out of place for eccentricity. ― Дрейгорич / Dreigorich Talk 22:05, 7 October 2019 (UTC)

The issue is a lack of number padding on the sort template, which doesnt seem to understand how numbers work. Will fix prompty. exoplanetaryscience (talk) 22:11, 7 October 2019 (UTC)

NEO page

Hi, It looks like you are the kind soul who's been keeping up the NEO flyby page List of asteroid close approaches to Earth in 2019 neglected since March, [3]. How much work is it to update? :) Tom Ruen (talk) 18:24, 20 October 2019 (UTC)

Hi Tom, I'm really sorry about that, it's been something I've been casually stressing over for a good while now. Essentially updating it now would be incredibly difficult, because approximately a quarter to a third of all close approachers never get confirmed, meaning that I would have to dig through NEOCP archives that no longer exist to get a list that's as thorough as I'd like it to be. Of course, I could just include the confirmed close approachers, but I don't think that would be very fair to have a completely blank region of 7 months where no close approachers were recorded. Basically, the data I would need to update some of this simply no longer exists, as far as I can tell. exoplanetaryscience (talk) 20:20, 20 October 2019 (UTC)

Supercavitation

Hi Exoplanetaryscience, I believe you added a copy editing maintenance template to the Supercavitation article on 2 July 2019. I made several copy editing changes to the article over the last few weeks. Could you please take a look at the latest version to see if the issues have been addressed? Thanks! CopyEditTechSurf (talk) 03:43, 7 December 2019 (UTC)

@CopyEditTechSurf: had a look, good job with that copyediting! It seems to address the somewhat disjointed tone of the article's sentences and sentence structure that prompted me to add the tag, so I'd say the issue seems properly addressed. exoplanetaryscience (talk) 04:24, 7 December 2019 (UTC)

2019–20 coronavirus pandemic data/United States medical cases : RECOVERIES

How is this going to be do-able? If we don't keep a breakdown per state, we will necessarily step on eachothers toes and double/tripple/etc count. I don't know what states you added recoveries for, so if I see recoveries for OH or NY, should I add them to the total? The only way to do this is a new table with per-state recoveries by day, as I can imagine some of them will not list totals, rather per-day numbers; as some states only list confirmed cases on a per-day basis.

At minimum, I think this should be broken down by state, as it will very quickly involve doulble-counts. Please consider removing the column, or supplementing it with its own table. For more ideas, move this to the discussion page of the template. dudzcom (talk) 22:46, 23 March 2020 (UTC)

I didn't make the column myself. Someone else made it and I assume they expected someone would add to it at some point. I for one definitely support adding a breakdown by state for recoveries but am not invested enough to write all of that down myself. exoplanetaryscience (talk) 23:08, 23 March 2020 (UTC)

Comet Atlas

There is a comet named Atlas on Wikipedia: (C/2019 Y4 (ATLAS), JPL). However I came across a two-year old Minor Planet Circulars (first page; Editorial notice) where the same name was given to another, periodic comet, P/2019 M2 (ATLAS) (JPL). In fact, there are about 47 comets named/discovered by ATLAS. Since these are all unnumbered, do you have any idea what nomenclature Wikipedia uses to distinguish these from another? Would it be similar to the numbered comets, such as Tempel 1 and Tempel 2? Thx Rfassbind – talk 23:42, 13 May 2021 (UTC)

Well I can certainly tell you the way the MPC distinguishes them- there was actually a discussion on the comets mailing list about it the other week - you are right that in the past they used to distinguish comets from one another by giving them a name ("Shoemaker-Levy 9" etc) apparently this process was officially stopped in the Marsden era for reasons I don't remember perfectly. Due to this, and some complicated factors with comet numbers (for instance, what about comets that weren't identified as comets until long after the fact? Are those numbered after newer ones, or do you make the newer ones higher-numbered retroactively?) I think it would be difficult/original research to go numbering them manually. Anyway, comets right now are officially only distinguished by their provisional name/number (C/2019 Y4, 2I, or 311P etc) and I would recommend marking them as such in all articles. exoplanetaryscience (talk) 00:32, 14 May 2021 (UTC)

Thx, just noticed your reply since Wiki did not ping me, sorry. So in the specific case of redirect Comet ATLAS, it should be a disambiguation page rather than a redirect to a specific comet, since more than one page/article on Wikipedia can be referred to (C/2019 Y1 (ATLAS), C/2019 E3 (ATLAS) and P/2019 LD2 (ATLAS)). Correct? However what about comets named after other discoverers such as NEOWISE? For example, Comet NEOWISE is the actual title of the article for C/2020 F3 (NEOWISE) from which it was recently moved after this approved request (RM) with the rationale that "this is the most notable comet that NEOWISE discovered", which would mean, in this case, Comet NEOWISE (disambiguation) plus a hatnote {{Other uses|NEOWISE (disambiguation)}} on top of article Comet NEOWISE would be needed/best practice. Of course the question remains who defines which body should be considered, and whether there is at all a "most notable comet" for a given discoverer (Pan-STARRS, LONEOS, WISE, LINEAR, Spacewatch, NEAT, etc.). Do you agree? What are your thoughts? Thx, Rfassbind – talk 11:13, 21 May 2021 (UTC)

Proposed deletion of Uranus trojan

The article Uranus trojan has been proposed for deletion because of the following concern:

List with two entries and no nontrivial sourced content. Not a set index article, as neither object is known as "Uranus Trojan".

While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{proposed deletion/dated}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the page to address the issues raised. Removing {{proposed deletion/dated}} will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion. –LaundryPizza03 (dc̄) 09:36, 21 January 2023 (UTC)

@NQue: hey, sorry for being a bit slow to reply. My source came from pages that this website no longer seems to have, but lurk somewhere in my computer.

Moon diagrams

Thanks for making those beautiful graphics!

Are you planning on doing Neptune? Double sharp (talk) 23:02, 29 January 2023 (UTC)

I got a little bit through a Neptune diagram but put it on pause for the difficulty involved. Unfortunately, Neptune's moon system is... problematic.

The outermost moons required me to resize the entire diagram just to fit them inside- Neso's orbit takes it from 27.7 to 72.4 million km from the planet, and Nereid's orbit takes it from 1.3 million to 9.6 million km from the planet. To add to that, Triton's status as the only sort-of intermediate moon means that the 'intermediate' section is almost entirely empty, the 'outer' section is chaotic and arbitrary, and the 'inner' section contains virtually nothing.

Here's that file: if you can identify how I can improve this while keeping thematically in line with the other planets, I'm all ears.

https://media.discordapp.net/attachments/591411532819333120/1069532787863986236/Neptunemoonsdiagram.png

exoplanetaryscience (talk) 08:22, 30 January 2023 (UTC)

Well, Neptune's system is quite weird compared to the other giants' systems, so I don't find this version problematic (well, I think the three sections should be swapped for consistency, with 'inner' on the top). It illustrates the situation well. Perhaps there should be an arrow in the 'intermediate' section indicating that Nereid's line continues further. (Are Psamathe and Neso cut off? I think the lines should only stop once we pass their apoapses.) Double sharp (talk) 14:08, 30 January 2023 (UTC)

All good points - Psamathe and Neso are just barely entirely in frame- just 9 pixels off in each case. If you couldn't tell for sure, though, that's one of those problems I'm talking about. It is an exceptionally chaotic moon system, sure, but my job has been and remains minimizing that chaos into something accurate but readable. Anyway, I'll make the changes recommended, add details (e.g. the compass, scale markers, and scale) and think of what to do from there. exoplanetaryscience (talk) 18:23, 30 January 2023 (UTC)

Looking forward to it! Indeed, Neptune's system is quite a mess, but I'd like to see it portrayed accurately for the mess it is. But that doesn't mean it can't be an exceptionally well-drawn mess. :) Double sharp (talk) 20:11, 30 January 2023 (UTC)

S/2020 S 4

Tilmann Denk thinks it may rather be an Inuit group member, because of its high inclination. He wrote on his website: Wikipedia classifies S/2020 S 4 as a member of the Gallic group of Saturn’s Irregular satellites. Because of the quite high orbit inclination of 43°, I think it might rather be a member of the Inuit group, possibly a collisional remnant of Siarnaq which shares similar orbital elements. Double sharp (talk) 14:00, 8 May 2023 (UTC)

Based on its oscillating elements, it's certainly a bit ambiguous, but I calculated its mean elements over 200 years and its mean inclination is only 41.1 degrees (oscillating from 33.5 to 48.0) with an eccentricity of 0.500 (oscillating from 0.347 to 0.664). The inclination is the most damning IMO, but it's worth noting that nothing in the outer Inuit group has an eccentricity above 0.311 (Siarnaq) while the entire Gallic group (with exception of 2004S24) has an eccentricity between 0.462 and 0.559. So, both the mean inclination and eccentricity make it seem fairly Gallic to me. exoplanetaryscience (talk) 14:09, 8 May 2023 (UTC)

Cool. I guess we'll probably know more in the future! Double sharp (talk) 14:27, 8 May 2023 (UTC)

@Double sharp: To preemptively defend categorizing 2019 S6 as a different group and to further explain 2020 S4's belonging to the Gallics, here's a diagram of (a vs e) (a vs i) (e vs i) showing the inuits in red, the gallics in orange, 2019 S6 in yellow, and 2004 S24 in green. 2020 S4 is smack in the middle for (a vs e) and the topmost gallic in (a vs i) and (e vs i). For another visualization, see the newest version of my diagram

All of these are the mean elements, which I can share if you like. Personally I would love to have the page include at least these provisional mean elements instead of these potentially very inaccurate oscillating elements, but that would constitute an egregious amount of OR. exoplanetaryscience (talk) 15:49, 8 May 2023 (UTC)

So, this is how I find out that five more were announced today! :D

I trust your categorisation. Maybe we should stop colouring S/2004 S 24 with the Gallics? :) Double sharp (talk) 16:43, 8 May 2023 (UTC)

I'm a fan of considering 2004 S 24 its own group/ungrouped - in fact, when it was originally announced I marked it on the page as its own group. Someone in the intervening time recategorized it as Gallic. I suppose if you want to group every moon, it makes sense, but IMO it has as much in common with the Gallics as the Gallics do with the Inuits. exoplanetaryscience (talk) 16:48, 8 May 2023 (UTC)

Makes sense to me. But I guess the flood of new discoveries hasn't stopped, so may as well wait a bit to do some recategorising. After all, maybe it will find some groupmates like Carpo did. So far I've mostly stuck to updating the count and the discovery timeline (well, and adding more and more discoveries to Scott S. Sheppard's page :D). Double sharp (talk) 16:53, 8 May 2023 (UTC)
