Is there any reference in Canon or Legends on how the hyperspace travel of the Death Star is performed?
Is it in anyway similar to the hyperspace travels performed by other starships in the Star Wars universe? Or is there another kind of ftl-drive I am not aware of?
I understand that a gaming book speculated that there were hyperdrive thrusters on the Death Star surface, but is this referenced anywhere else? As a more technical approach, how would a massive body like this would achieve integrity in a hyperspace jump? Would all of these supposed hyperdrive thrusters need to be synchronized before the jump in order for the entire Death Star jump?
