The brown dwarf Doornik-1142
A brown dwarf can be described as a star in the process of its birth. They did not have enough mass to sustain the nuclear fusion of hydrogen, and at times, people thought of them as massive gas giants. These brown dwarfs comprised only a tiny percentage of the stars in the galaxy, and it was thought that they could not support life.
During the era of the Galactic Civil War, the section of space separating the planets Kupoh and Gamorr had not been thoroughly explored. Luke Skywalker believed that this region might contain unmapped brown dwarfs, posing a potential threat to hyperspace navigation. One example of a brown dwarf star was Doornik-1142.
