Nul II is the second planet from the sun of the unclaimed Nul system. Large and dense, it is composed mostly of iron, and is thought to be the former core of a super-Earth that lost its mantle. While there is no water to be found, there are many lakes on the planet, including straw-colored lakes of iron carbonyl.
