Enceladus
Saturn's tiny moon with geysers and a hidden ocean/Moons
Enceladus is only 504 km across but punches far above its weight in scientific interest. The Cassini spacecraft discovered enormous plumes of water ice erupting from cracks near its south pole, hinting at a subsurface ocean beneath the icy crust. This makes it one of the most promising places to search for extraterrestrial life, assuming alien microbes enjoy extremely cold salt water.
