Second Death Star

As referred to in canon texts, the Second Death Star was the Death Star that Palpatine had built around the forest moon of Endor, in Star Wars: Return of the Jedi. It was destroyed by a tandem flight by Lando Calrissian on the Millennium Falcon and Wedge Antilles in an X-Wing Fighter.

It is rumored that since this space station was still under construction, the Rebels killed innocent contract laborers in the attack. See: Clerks
