This object is home to a light-colored grooved terrain known as Uruk Sulcus, as well as the Osiris and Tros craters.
This object is home to a light-colored grooved terrain known as Uruk Sulcus, as well as the Osiris and Tros craters. However, it is the Anat crater on which this object's coordinate system is based. The grooved surface of this moon may have been the result of tidal heating caused by Laplace resonances, which would have pushed its orbital eccentricity far above the .0015 value this moon has today. A saltwater (*) ocean is believed to exist below its sulfate-rich surface, but above the liquid iron crust, which is the site of convection. The Hubble Space Telescope found a thin ozone atmosphere around this body, but it is better known for having a strong magnetosphere. For 10 points, name this Galilean moon of Jupiter, which is also the largest moon in the solar system.
