# Why 225088 Gonggong is not a dwarf Planet yet?

Per definition a dwarf planet is:

a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape1, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.

The Wikipedia page for 225088 Gonggong, former 2007 OR10 states three possibilities for its dimensions:

• 1535+75−225 km
• 1280+210−210 km
• 1200+300−200 km

Which is all minimum 1000km in diameter. So how can you still doubt the hydrostatic equilibrium for such a large body?

• I think your Wikipedia link answers the question - that researchers agree it is probably a dwarf planet. Or is your question more about the process to get it officially recognised as one? – Andy May 17 '16 at 7:22
• I just don't understand the remaining problem? Why should it not be a dwarf planet? What are the remaining doubts? – rubo77 May 17 '16 at 7:45
• I would guess it just needs to be recognised by some committee somewhere ( the IAU perhaps) to be officially added to the list. And get given a proper name. – Andy May 17 '16 at 7:55
