Almost every ship (excluding speeders and small fighters) in the Star Wars universe can travel at light speed. As far as I'm aware most space stations can't (Bespin certainly doesn't seem to).
The Death Star is shown to move very slowly (at least it gives them plenty of time while orbiting Yavin). However it also appears to move between star systems.
Can the Death Star travel faster than light? If so is this common in the Star Wars universe?
