What Is the Quadruple Star System? The system contains four celestial bodies grouped in two pairs. One pair is young red dwarf stars, common and relatively bright. The other pair consists of cold brown dwarfs, faint objects about the size of Jupiter. The brown dwarfs orbit the red dwarfs in a hierarchical arrangement. This system is unique because brown dwarfs rarely have companions and are seldom found in multiple-star systems.
