# Since Vesta is rotating, could you dig a habitat into it near the poles?

Would building a crescent shaped habitat work if you didn't want to go all the way?

Edit: I'm asking if this would be enough to provide artificial gravity, sorry not not being clear about it.

• You dig into the asteroid far enough to cover the outer surface of the habitat (which would be more of a semi-circle or a quarter than a crescent shape) with 3d printed regolith. Taking advantage of the asteroid's spin without it being a full circle. Commented Mar 30, 2021 at 0:21

• If you use the full radius (262 km) and the rotation rate of once per 5.34 hours I get .003 g's at the equator, so probably not worth bothering with. Please check my math though. Commented Mar 30, 2021 at 0:46
• @OrganicMarble it's worse, since the surface gravity is 0.025 g in the other direction. You'd just be picking the part of the asteroid where the effective surface gravity is the lowest. The poles would be better because the two vectors wouldn't be opposed, but the amount it'd add wouldn't be worth thinking about. Commented Mar 30, 2021 at 1:53
