Mass limits[edit]

We say there are no planets beyond Neptune, but the calculations were based on data from 1990. What are the constraints today? Can we give upper masses for regions beyond Neptune? What about things out of the ecliptic? — kwami (talk) 00:22, 9 January 2014 (UTC)

There are possibly rather heavy objects. What they didn’t achieve, though, is clearing the neighbourhood…. Incnis Mrsi (talk) 11:28, 9 January 2014 (UTC)

Vp113[edit]

I am currently only able to access the Internet via iPad, so I dont have the tools to do this myself but any info regarding vp113 has to go in the susequent proposed section until the supposed planet is confirmed.Serendipodous 12:52, 27 March 2014 (UTC)

Where would you put it? Under the heading '2012 VP113' at the end of the section 'Subsequently proposed trans-Neptunian planets'? --Eleassar my talk 13:53, 27 March 2014 (UTC)
The big problem with 2012 VP113 is that it does not prove any object of several Earth mass exists hundreds of AU from the Sun. There are many possible explanations for 2012 VP113, 90377 Sedna and 2000 CR105. People always jump on Planet X because it sounds exciting. -- Kheider (talk) 14:02, 27 March 2014 (UTC)
Well, it is an actual possibility, so this article should explain this to be comprehensive. --Eleassar my talk 14:34, 27 March 2014 (UTC)
I have added it to the Kuiper cliff section. It is pretty much the same story as Sedna. -- Kheider (talk) 14:39, 27 March 2014 (UTC)
It's a bit more complex than that Kev; I've expanded it a bit to clarify the "Planet X" connection.Serendipodous 16:24, 27 March 2014 (UTC)
We do not have a section dedicated to Sedna. Hopefully in a few years we will have references that discuss Sedna and VP113 as a group and we can expand the Kuiper cliff section or have a section called Sednoids. -- Kheider (talk) 16:58, 27 March 2014 (UTC)
