This body is the primary home of the so-called dark ray craters, which are concentrated on the trailing hemisphere of this synchronously orbiting body.
This body is the primary home of the so-called dark ray craters, which are concentrated on the trailing hemisphere of this synchronously orbiting body. It is also home to the large Gilgamesh impact basin. Its trailing hemisphere is a primary site of ozone production as its water ice surface is blasted by charged particles trapped in the Jovian magnetosphere. Evidence for its having a rocky core includes detection of its own magnetosphere by the Galileo orbiter. Displaying three crater chains similar to those found on its neighbor Callisto, FTP name this largest moon of the Solar System.
