Ceres is spherical, Vesta isn't – is it the largest non-spherical solid body in the solar system?

I was showing a recent video about Ceres to a friend and we looked up asteroids. Ceres has attained a fairly spherical shape, but Vesta still has a way to go. From Wikipedia:

Vesta's shape is close to a gravitationally relaxed oblate spheroid, but the large concavity and protrusion at the southern pole (see 'Surface features' below) combined with a mass less than $5×10^{20}$ kg precluded Vesta from automatically being considered a dwarf planet under International Astronomical Union (IAU) Resolution XXVI 5.

I don't know the proper term to use here. Perhaps it is "hydrostatically relaxed" or something similar – I'm looking for the term that would suggest a body has reached a fairly round shape without major excursions, under the influence of its own gravity.

I think Ceres meets this criterion, and Vesta doesn't. Is Vesta the largest such body (by dimension or volume, not sure which would be the most reasonable measure)?

• @userLTK that is absolutely fascinating! I've asked a follow-up question. Thank you for that! – uhoh Nov 27 '16 at 7:36
• I couldn't find tags for planetoid or planetessimal, would something like these be appropriate now? – uhoh Feb 4 '18 at 17:35
• @Chirlu I've moved the sentence you proposed deleting into a comment, then accepted your edit. It should have been a comment from the beginning, however next time consider moving rather than simply discarding helpful suggestions. – uhoh Feb 4 '18 at 17:37
• @uhoh: OK, but I thought after more than one year, it's not going to happen anyway. ;-) In any case, as it is now, it is properly associated with your account. – chirlu Feb 4 '18 at 18:02
