At a diameter of 250KM, and with enough gravity to retain rings, does that mean it also possesses enough gravity for hydrostatic equilibrium?
If so, this qualifies it officially as a dwarf planet.

- JFFalcon 8y agohttps://en.wikipedia.org/wiki/Hydrostatic_equilibrium#Planetary_geology https://en.wikipedia.org/wiki/Hydrostatic_equilibrium#Planet... claims the limit of hydrostatic equilibrium for rocky bodies is ~400-500km, so probably not.

- rbanffy 8y agoWith a diameter of 160 Km, it'd be the smallest one, by far. This is particularly interesting because I don't think there's anything round with this size in the system - and a circular ring indicates that. Do we have instruments able to directly image it?
