Usus

Usus (pronounced "Oo-sus") is the second planet in the SuS system of planets. It is a medium-sized terrestrial planet, with much of its surface being covered with liquid water. It has a few craters on it, and has a somewhat thick atmosphere. It is a habitable planet, however no life has been discovered on it as of yet. It has one moon, called Canada.

It is rather similar to Nexon in composition and size, leading some astronomers to believe that they either formed in the same part of the SuS system, or were once both part of one huge terrestrial planet which somehow got split in two.
