Gelop |\|\| is the second of the volcanic moons of Gelop, and is smaller than the other, being only around 1.6 Mm in diameter. Like Gelop Du, it has a constantly shifting surface punctuated by the occasional volcanic eruption, however underneath the rocky surface lakes of liquid water have been found. Whilst there are no permanent residents on the surface, it has several remotely operated surface bases for the storage of light weaponry to temporarily defend the moons of Gelop.
