What does "SO" stand for? edit

Should be explained in the article. — Preceding unsigned comment added by 83.254.28.239 (talk) 11:12, 5 December 2020 (UTC)Reply

Just an alphanumeric counter: 2020 SM, 2020 SN, 2020 SP, 2020 SQ. --Voidvector (talk) 21:33, 13 December 2020 (UTC)Reply
@83.254.28.239: The name indicates the minor planet was 14th discovery of minor planet (O) in the period from September 16 to 30 (S) in 2020 (2020). See Provisional designation in astronomy#New-style provisional designation.―― Phoenix7777 (talk)

MoS WP:ELPOINTS edit

WP:ELPOINTS

  • Links in the "External links" section should be kept to a minimum. -- there are 27 external links now.
  • In the "External links" section, try to avoid separate links to multiple pages in the same website, as if to provide a portal to that website -- this has been done three times now.

Do you think it matters?

Not a minor planet edit

This should not have the planetbox anymore because it is actually space junk.Kepler-1229b talk

As it has a minor planet designation it seems counter productive to remove the infobox. 2006 RH120 and 6Q0B44E both use Template:Infobox planet. -- Kheider (talk) 17:42, 30 December 2020 (UTC)Reply
2006 RH120 is a minor planet. Kepler-1229b talk
I do not think the nature of 6R10DB9 (2006 RH120]) has been resolved with 100% certainty. -- Kheider (talk) 09:52, 8 January 2021 (UTC)Reply

orbital eccentricity edit

Not sure what the editor was trying to say here:

As it approached Earth the trajectory indicated the geocentric orbital eccentricity was less than 1 by 15 October 2020

All orbits have an eccentricity of less than 1, or they aren't orbits, they are straight lines. An eccentricity of 0 is a perfect circle.--MadeYourReadThis (talk) 22:28, 31 January 2021 (UTC)Reply

A geocentric orbit is not the same as a heliocentric orbit. But the object also needs to be within Earth's Hill sphere to truly be in orbit. An object 1AU from Earth could have a geocentric e<1 if the relative velocities are small, but we would not say it is orbiting Earth.-- Kheider (talk) 23:30, 31 January 2021 (UTC)Reply
