Talk:Margaret (moon)

Untitled

Pronunciation per the OED, tho not precisely for the Shakespearean character, is UK mar'-g@-rit or mar'-grit, with the unaccented i being a high schwa, of course, and US mar-gr@t. kwami 20:27, 3 November 2005 (UTC)

reason for name

Perhaps why the Much Ado reference was made in the naming from the works of Shakespeare(using a much lesser-known Margaret when other Margarets are in the historical plays) -- it pokes fun with an inside joke about the current real world Much-Ado being made about 2003 EL61, 2003 UB313 and Pluto and names, and naming, etc. --69.173.148.39 21:40, 5 November 2005 (UTC)

This edit had deleted the following:

And also, you've missed why the Much Ado reference was made: it's an injoke among the discoverers about the current real world Much-Ado being made about 2003 EL61, 2003 UB313 and Pluto and names, and naming, etc. --Sturmde 17:04, 4 November 2005 (UTC)

Blimey, that's way too subtle for me. My guess is it's named after someone's mother, and they found a name from Shakespeare to justify it! The Singing Badger 21:46, 5 November 2005 (UTC)

@The Dancing Badger: Turns out, you were right! Scott Sheppard said on this podcast: I just simply did a search for "Margaret," which was my Mom’s name, on the Web, and "Shakespeare," and it came up with Much Ado About Nothing. :D Double sharp (talk) 23:22, 27 November 2021 (UTC)

Sturmde (I just restored his comment, which I had copied from another page) states that it is an in-joke; perhaps he has evidence to back up this assertion. If he does (Sturmde? Are you out there?), this would be nice to include in the main article. kwami 22:02, 5 November 2005 (UTC)

Retrograde

Sentence from article: "It stands out from the Sycorax group by its inclination, which is only 56.63°, whereas all of the Sycorax group moons are retrograde, with inclinations in the 140-170° range. "

So does Margaret have a retrograde orbit or not? Rmhermen 19:25, 6 November 2005 (UTC)

No, it does not. Their are two ways of indicating a retrograde orbit. A retrograde moon inclined by 10°, in a 6-hour orbit, could be said to have the orbital parameters of 10° and −6 h (in which case no inclination ever exceeds 90°), or of 170° and +6 h (in which case no period is ever negative). It's more common to keep the period positive and let the inclination vary between 90°-180°. You see the same thing with Uranus' inclination vs. rotation. However, Venus is more commonly given a negative rotational period, both because it's so close to zero anyway, and because this gives it an inclination close to its near-twin Earth's. I suppose if we could ever reconstruct whether the impact that walloped Venus early on flipped it over or just reversed its rotation, we'd see a preference for one or the other. kwami 22:53, 6 November 2005 (UTC)

I added some of this to the retrograde article. Rmhermen 17:00, 26 November 2005 (UTC)

how i stumbled across those page (trivia)

When searching for Margaret_Hamilton_(software_engineer), that took the lead in the software part for the Moon trip (the one with the first landing) - i saw this page popping up in Google. First hoping this "other" moon was dedicated to her, but then finding out it was not. Despite this it would have been an adequate honor for her due to her exceptional contribution that was reaching far beyond the state of the art of her subject, and in a quality scope is still unmet by even the majority of software products of our present times. --Alexander.stohr (talk)
