Death Star
The Death Star is a type of fictional mobile space station and galactic superweapon featured in the "Star Wars" space opera franchise. The first Death Star is stated to be more than 100 km to 160 km in diameter, depending on source. It is crewed by an estimated 1.7 million military personnel and 400,000 droids. The second Death Star is significantly larger, between 160 km to 900 km in diameter depending on source, and technologically more powerful than its predecessor. Both versions of these moon-sized fortresses are designed for massive power-projection capabilities, capable of destroying multiple naval fleets or entire planets with one blast from their superlasers.
Endor (Star Wars)
In one of the "Star Wars Tales" comics, an Imperial veteran of Endor refers to the moon being devastated by the impact of falling debris from the Death Star, which was blown up while in orbit around the moon. However, another character dismisses this as a myth, saying that most of the Death Star's mass was obliterated in the explosion, and that the Rebels "took care of the rest."
