Earhart is a gas giant, similar to Neptune. Its largest moon, Jernar, is almost completely covered in water.
Gas giant, it does not have geography. It's atmosphere mostly consists of hydrogen and watervapor.
Like most (not all) gas planets there is no life that is not introduced by intelligent species. Some life that is introduced by these are the Guatuer and the Resolon.
There is almost nothing to see here except the few gas extraction facilities.
