Centax 3

Centax 3 was a location in the galaxy. Shortly after the destruction of the planet Alderaan, an Alderaanian resident of the planet Coruscant named Anandra Milon asked an old man running the stall known as Hangra's Meat Shack about a "Centax 3 delivery". The man did not know what she was talking about and eventually took pity on her, giving her a small amount of food.

Behind the scenes
Centax 3 was originally established to be one of the moons of Coruscant by the source book Coruscant and the Core Worlds, released by Wizards of the Coast in 2003. This information however, part of the Expanded Universe, which is no longer considered canon. Centax 3 was first mentioned in canon in "One Thousand Levels Down" a short story by Alexander Freed which was published in Star Wars Insider 151 in 2014. The story does not re-establish that the location is a moon of Coruscant however.
