Tanalou, situated in the Varada sector of the Outer Rim Territories', was a frigid, rocky planet devoid of any moons. It orbited the yellow star Baralou as the fifth and most distant orbital body in the Baralou system.
The initial reference to Tanalou appeared in Planets of the Galaxy, Volume One, a 1991 publication that served as a resource for West End Games' Star Wars: The Roleplaying Game. Later, in 2009, The Essential Atlas specified the location of the Baralou system, and consequently Tanalou, within grid coordinate H-20.
