Callisto


A Callisto globe (Jupiter IV), the third largest moon in the solar system and the second largest of the four Galilean Satellites. 

Callisto possesses a surface speckled with crater and high high albedo features that makes it seem as if the moon is sparkling.

It's distance from Jupiter, placing it beyond Jupiter's deadly radiation belt makes it a primary candidate for colonization as humanity seeks to expand to the outer solar system.
