Naxook
From Halopedia, the Halo wiki
Naxook, along with Oquiu, Ka'amoti, and Kami, is a satellite (moon) orbiting the planet Palamok, which is the home planet of the Drones.[1]
Due to the increased gravity of Palmok and Albert Einstein's theory of gravity binds, in which the size of a body in space decides the distance in which it takes before something falls onto orbit or becomes too close to the body and collides. Therefore, Naxook must be about twice the distance from Palmok as Luna is from Earth due to the gravity being twice that of Earth.
