To-do
[edit]Abandoned, I realized I'm not going to follow half of these anyway
- UPDATE THESE ARTICLES WITH TOP PRIORITY:
- WISE 0855−0714
- Review all articles under Category:Comets
- Articles may be miscategorized, or not categorized at all.
- Talk pages don't have both WP:ASTRO and WP:SS templates.
- Designation-only articles must be moved to include discoverer names.
- If an article cannot be moved due to CAPS limitation in the title, then request for move.
- Some comet stubs don't have infoboxes (e.g. C/2014 Q1 (PanSTARRS))
- Fix category sorting
- Natural satellite list cleanup & update (https://ssd.jpl.nasa.gov/sats/elem/)
Moons of Jupiter(add images later)Moons of Saturn(add images of Albiorix, Skoll, and Loge)- Moons of Uranus (add image of Francisco)

Sedna controversy
[edit]- Alain Maury - https://www.spaceobs.com/en/Alain-Maury-s-Blog/How-he-believed-he-killed-Pluto-alone-and-why-it-had-it-coming
- In attempt to thwart Brown's eventual "illegal" naming of Sedna, Reiner M. Stoss proposed to name his discovery (60175) 1999 VQ1 after Canadian singer Katy Sedna before the numbering of 2003 VB12. The so-called "Yahoo chat group" mentioned by Brown in his book and blog was referring to the MPML.
- Stoss's disclosed naming proposal, "short and crispy":Discovered 1999 Nov. 3 at the Starkenburg Observatory, Heppenheim.
Named in honour of Sedna, the Inuit goddess of the sea. [6]- The proposal was then revised to: Discovered 1999 Nov. 3 at the Starkenburg Observatory, Heppenheim. Named in honour of Katy Sedna, singer and songwriter. Raised in Africa, the US and Europe she studied songwriting and vocal improvisation at Berklee College of Music in Boston, USA. She has a most unique way of presenting her songs, revealing her playful spirit and her deep sense of optimism.
- Stoss was informed (or in his case, "blackmailed") by a CSBN member to change the proposed name from "Sedna" to "Katysedna" by September 28, otherwise his options are to change the name or withdraw the proposal. The proposal was subsequently withdrawn and Stoss was adjured by the CSBN (Jana Ticha) to apologize for his "objectionable behavior."
- Marsden's response to Stoss's proposal: "That is an even nicer try, and I have included your proposal in the set of names for consideration for the July MPCs." [7]
- Marsden, continued: "But this whole sorry episode shows that your time-wasting tactics. These annoyed many people, and they have accomplished essentially nothing." [8]
- "Fact is that my second naming proposal for the singer Sedna (which could not be rejected lawfully) was submitted months before 2003 VB12 got even numbered. It was intentionally withheld until 2003 VB12 would become eligible for naming. It was therefore not "quickly" that the secretary of the CSBN realized something but he withheld the rightful proposal for months until the unlawful proposal could get the formal vote. It was a plot between Brown (discoverer of 2003 VB12 aka Sedna), Marsden (director of MPC and secretary of CSBN) and Ticha (chair of CSBN) right from the start." [9]
- Stoss's disclosed naming proposal, "short and crispy":Discovered 1999 Nov. 3 at the Starkenburg Observatory, Heppenheim.
- Bill J. Gray was particularly against Stoss's crusade against Brown's premature naming of Sedna.
- I'm sure someone is thinking of doing this [proposing the name "Sedna"]. If so, I'd ask you to please reconsider. We've had enough embarrassments over the last few years. [10]

- Total of 49 observers across Europe and Asia. 37 telescopes located within nominal predicted path: 21 positives, 16 misses. An additional 12 telescopes were located far from the path to find rings or moons.
- Area equivalent diameter 411.0 ± 7.3 km, consistent with Herschel estimate of 406 ± 16 km.
- Albedo 0.079 ± 0.004 based on corrected individual abs mag of Hv=5.31
- New rotation period 6.725 ± 0.006 h obtained from recent observations combined with older datasets
- Aliases of new rotation period still cannot be ruled out
- Size corresponds to likely density of 0.8 g/cm3
- Maclaurin or Jacobi ellipsoid? Non-equilibrium? (True shape unknown)
- Upper limit atmospheric pressure 10 nbar
- Likely not in hydrostatic equilibrium
- Moon not detected

[edit]- thermal flux directly gives diameter, which then allows albedo to be determined: "the measured thermal flux yields the object’s (surface-equivalent) diameter D, and the albedo is then determined from the usual relationship between diameter D and H magnitude..."
