Vesta has a surface gravity of 0.022 g’s, which would make me weigh about four pounds without a spacesuit. Escape velocity is .35 km/s, which means you might drift up but you’d drift right back down again.

Ceres’ numbers are larger, but not by too much.

Is it enough to allow a spacecraft to land, or for a man in a pressure suit to walk without drifting off? I wonder what the gravitational acceleration is at the surface.
