Funnily, Trujillo's nickname for 2012 VP113 is 'Biden'! — Preceding unsigned comment added by 66.186.163.112 (talk) 00:15, 27 March 2014 (UTC)

Questions

What is an "argument of perihelion"? How does it "...indicate a similar formation mechanism for these bodies"? Abductive (reasoning) 18:02, 27 March 2014 (UTC)

It is one of three parameters that indicate the orientation of the orbit. It can be best be understood by varying these values in Celestia (or a similar program) and see the effect on the orbit. In this context it comes down to the fact that 2012 VP113's and Sedna's orbits are rather similarly oriented. --JorisvS (talk) 18:10, 27 March 2014 (UTC)

Are they going to give it a real name?

I hate it when they leave a discovery with a long. boring number for a name. This thing is a dwarf planet. Give it a cool name! 2602:306:BDA0:97A0:466D:57FF:FE90:AC45 (talk) 14:21, 3 April 2014 (UTC)

If 2007 OR10 still doesn't have a name, I wouldn't hold my breath for this one. Serendi^podous 15:11, 3 April 2014 (UTC)

Biden is a pretty cool name, don't you think? Jonathunder (talk) 16:14, 3 April 2014 (UTC)

It is cool, but Biden will probably not be the official name of 2012 VP113. The International Astronomical Union does not allow objects to be named after politicians until they have been dead for at least 100 years. Apogalacticon (talk) 17:37, 3 April 2014 (UTC)

Buffy (discovered in 2004) still does not have a name. License plate numbers are common. -- Kheider (talk) 11:24, 6 April 2014 (UTC)

Miles

Rather than edit warring. I suggest that the use of the common (nonscientific) unit "miles" is an innocent usage and should be let stand for those who are not scientists. WP:NOTJOURNAL items 6, 7, 8 TomS TDotO (talk) 18:35, 3 April 2014 (UTC)

We don't do that. It's an editorial choice we have made as per the science articles on this site. Serendi^podous 19:18, 3 April 2014 (UTC)

I agree, particularly since the source gives 450 km as a rough estimate of diameter; "279 miles" is meaninglessly overprecise. Jonathunder (talk) 21:30, 3 April 2014 (UTC)

Nickname

Looking at the recent edit history, there seems to be a bit of dispute over whether the Nickname section should use "...after Joe Biden, the vice president..." or "...after Joe Biden, who at the time of discovery, was vice president...". From the edit summaries, I believe the editor in favor of the more verbose wording argues that the shorter sentence will be inaccurate when Joe Biden leaves office, while at least one of the two editors who favor the shorter sentence argues that the longer sentence implies Joe Biden has already left office. In an effort to resolve this dispute, I've used the {{show by date}} template to have the text automatically switch from "...after Joe Biden, the vice president..." to "...after Joe Biden, who at the time of discovery, was vice president..." on January 20, 2017 (the date that Joe Biden is scheduled to leave office). Is this an adequate solution? —RP88 ^(talk) 06:29, 10 April 2014 (UTC)

Joe Biden will always be the VP when VP113 was discovered, so there's no need to change the wording when he leaves office. Isn't it a little obvious that, when discussing events in 2013, those events took place in 2013? We can say that King Louis XVI was executed by the French Revolution. We don't need to say "Louis XVI, who at the time was king". — kwami (talk) 06:46, 10 April 2014 (UTC)

Do I personally think the "who at the time of discovery" wording is necessary? No, I do not. However, after Joe Biden has left office it certainly would not be wrong, perhaps over-obvious, but not wrong. My introduction of the {{show by date}} was just an effort to resolve the slow-motion edit dispute. I would not object if the text was switched back to the shorter sentence. —RP88 ^(talk) 07:04, 10 April 2014 (UTC)

Lead paragraph

The current opening sentences read: "2012 VP113 is a planetoid in the outer reaches of the Solar System. It is the object with the largest known perihelion (closest approach to the Sun) in the Solar System, larger than Sedna's." Which gives the impression that the object passes inside the orbit of Mercury. I think it should read "It is the object with the smallest known perihelion (closest approach to the Sun) in the Kuiper Belt, less than Sedna's." But as this isn't my main area of expertise I'd prefer someone to review the change first. Thanks. Perry Middlemiss (talk) 23:12, 6 September 2015 (UTC)

The word should be "farthest". Serendi^podous 23:22, 6 September 2015 (UTC)

Yes, that's better.Perry Middlemiss (talk) 12:00, 9 September 2015 (UTC)

Biden

We need an admin to move this back to 2012 VP113 as Biden is not an official name for this object. -- Kheider (talk) 19:38, 5 November 2017 (UTC)

 Done. No admin needed, really, but I've added this back to my watchlist. Primefac (talk) 19:54, 5 November 2017 (UTC)

Orbit, presumed Trans-Neptunian planet

In fact, all known Solar System bodies with semi-major axes over 150 AU and perihelia greater than Neptune's have arguments of perihelion clustered near 340 ± 55°.

This was true as of 2014, but is now outdated. In fact, as Planet_Nine#Extreme_trans-Neptunian_objects shows, it is no longer true even for the majority of distant objects. Those do show some form of clustering, but in a different region of the parameter space. For instance, the argument of perihelion shows no clustering at all. The article should be updated to reflect the new data.--Renerpho (talk) 06:12, 13 March 2018 (UTC)
