Can new minor-planet names still conflict with moons?

Hi,

Nyx was rejected for Pluto II in I believe 2006 due to conflict with an asteroid (resubmitted as 'Nix' and accepted that year), and similarly a bit later with Kerberos vs Cerberus, but Romulus had been accepted for Sylvia I in 2005 (or at least the circular was published in August that year) despite a similar conflict. I don't recall however who exactly nixed 'Nyx', and don't know whether it's now MPC policy that names must be unique among both minor planets and moons, or if something else happened with Pluto II and IV. Do you have any idea?

I added this to minor-planet designation, but don't want another spurious 'fact' that goes unnoticed. — kwami (talk) 05:20, 24 March 2026 (UTC)

Thanks for the reminder, Kwami -- I'll look into it. Renerpho (talk) 07:21, 1 April 2026 (UTC)

Jupiter

I just confirmed some Jupiter MPECs got skipped. Cited my source in the update. We're at 115 now as of G75. Saturn I'm less certain and I don't want to accidentally double count. ~2026-21979-97 (talk) 23:49, 9 April 2026 (UTC)

I also counted Saturn's MPECs for the ninth. There are seven new moons. I think you might have accidentally counted in some asteroids or Jovians. It's 292 as of G75. ~2026-21979-97 (talk) 23:54, 9 April 2026 (UTC)

@~2026-21979-97: Thanks! You're right about me miscounting. I counted all of G65 through G75 as moons of Saturn, when four of these were in fact moons of Jupiter (these bringing the count for Jupiter from 111 to 115). Renerpho (talk) 00:07, 10 April 2026 (UTC)

2006 RH120

Nicely done although a full on prize requires that you take the photo yourself (the approach I had in mind here was waiting for 2028 and then going after it with one of those remotely operated telescopes). It certainly gets you an Honourable mention mind. Been a bit of a year for people knocking things off the list and 2006 RH120 is the third space based one to go (although in the case of Kosmos 482 its because it probably no longer exists).©Geni (talk) 09:28, 29 May 2026 (UTC)

@Geni: Hehe, no problem! I take the honorable mention. Happy to knock it off the list. I think it would have been too faint (peaking at 23 mag, not within reach of any remotely operated telescopes) during its 2028 approach.

As a bonus, there are some additional observations from 2006 that were uncovered in the process of making this, which extend the arc of 2006 RH120 back by a few days -- to be published in the coming days, hopefully. That should make predictions of its future position a bit more accurate (it is strongly affected by non-gravitational forces). Renerpho (talk) 09:34, 29 May 2026 (UTC)
