Cosgroveball is a moon of Uranusball. Mirandaball is the smallest, closest and ugliest round moon of Uranus. While astronomers from Earthball aren't sure how her rugged terrein formed, the most likely hypothesis is that she collided with another moon, bursting her apart, then she reformed. She contains the deepest ridge in the Solar System, at about 5km to 10km and if a ball was dropped from the top, it would take 10 minutes to get to the bottom. Like the other moons of Uranusball, It is possible that she has a subsurface ocean (as a result of tidal forces) where aquatic 6balls roam.
