Jestan was a planet of the terrestrial type. It existed within the Jestan system and was classified as a planet. Its location was within the Corpheli sector of the Expansion Region. More specifically, it was situated in both the Outer Expansion Zone and the Northern Dependencies, which are parts of the aforementioned region. Jestan was positioned along a key hyperlane that connected it to both the Belukat and Corphelion systems.
By the year 2 ABY, the Rebel Alliance achieved victory on Jestan. This victory occurred during a significant battle against the Galactic Empire in the Galactic Civil War. This conflict became historically known as the Engagement at Jestan. Sometime between the years 12 ABY and 13 ABY, Jestan came to be included within the territorial boundaries of the New Republic.
The name of Jestan initially appeared in Alliance Intelligence Reports, a 1995 sourcebook for Star Wars: The Roleplaying Game by West End Games, where the Engagement at Jestan was mentioned. Later, in 2008, The Complete Star Wars Encyclopedia formally identified Jestan as a distinct planetary body. The 2009 reference work, The Essential Atlas, pinpointed the location of the Jestan system, and consequently the planet itself, to grid square M-7.
