A comment on First Ring System Around Asteroid (2014).

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.

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

With 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?

The dimensions listed are 296 × 264 × 204 km. It’s kind-of round-ish, but not spherical.
