Ioball

Ioball is a moonball of  Jupiterball.

She is the closest visible moon of Jupiterball, if you look with a small telescope. She is still very mad because of Jupiterball's strong gravity which creates tital heating making Io the most volcanically active body in the Solar System.

Composition
Ioball is the densest of the Galilean Moons. She is known for her vivid colors, caused by the deposits of multiple sulfer alletropes by her many volcanoes. She contains a large silicate and iron content.
