Aaghra

Aaghra was a planet within the Zug system of the Core Worlds region. It was incapable of supporting life, thus having no affiliation whatsoever. The planet was discovered somewhen between 25,000 BBY and 17,000 BBY.

History
Aaghra was the first planet from the star Zug in the Zug system of the Core Worlds region, not far from Coruscant, the most politically important planet in galactic history. It was a moonless world of molten rock, which thus lacked suitable terrain for life. The planet also lacked both water and habitants, therefore having no political affiliation whatsoever. While it didn't have any official affiliation, the Zug system, including Aaghra, was considered part of the Galactic Republic and consequently became part of the Galactic Empire's space when the Republic became the Empire in 19 BBY. From then, it became part of the New Republic in 8 ABY and more than a hundred years later, as part of a new Galactic Empire. Aaghra had a Type IV atmosphere, where the use of an enviro-suit was required to travel safely on or near the surface. The planet was discovered by the galactic community sometime between 25,000 BBY and 17,000 BBY.

Behind the scenes
Aaghra was first mentioned briefly in part one of the Planet Hoppers article Aargau: For All Your Banking Needs, which was written by Cory J. Herndon and published on the Wizards.com website in 2003. After being mentioned again in The Essential Atlas (2009), an Essential Guide written by Jason Fry and Daniel Wallace, the planet hasn't been referenced in any other Star Wars products so far.
