Encedladus is the smallest geologically active body in the solar

system, the only asteroid-size one. Could be a gravity tidal thing.

It's the same size as a country in Africa. Its smooth surface, hence

younger than the early bombardment era, matches geological activity:

the surface gets renewed. Only the Earth, Mars, and Io are geologically

active too, and the Moon seismically only.
