Looks like it has almost, but not quite, reached hydrodynamic equilibrium (collapsed into a sphere). Close but no cigar.
It would be cool to go there, set up a very large inflatable tent on the surface and mine gold in your shirt sleeves.
The gravity is something like 0.25 m/s^2 (~2.5% of Earth) so hopping around would be a lot of fun for a while. Picking up large boulders in your hands and moving them around like nothing would make for a great YouTube video.
4 Vesta
Vesta, minor-planet designation 4 Vesta, is one of the largest objects in the asteroid belt, with a mean diameter of 525 kilometres (326 mi). It was discovered by the German astronomer Heinrich Wilhelm Olbers on 29 March 1807 and is named after Vesta, the virgin goddess of home and hearth from Roman mythology.
Vesta is the second-most-massive and second-largest body in the asteroid belt after the dwarf planet Ceres, and it contributes an estimated 9% of the mass of the asteroid belt.
It is slightly larger than Pallas, though significantly more massive.
Yeh it kind of almost a sphere and appears to have a differentiated interior which suggests it almost makes the grade.
