[Star Wars] How does the Deathstar move?

Are there like some thrusters hidden underneath it that we just never see in the movies?

The Death Star had giant ion engines which only failed to strike terror into its enemies because of the overwhelming scale of the rest of the construct. These ion engines provided thrust through space, such as maneuvering around Yavin's gravity well or orbital station-keeping at Endor.

The Death Star also had several vast and interlinked hyperdrive generators (backed by formidable computing power) which allowed it to move rapidly around the galaxy's Outer Rim. 

Both of these systems, and the main superlaser, were powered by a hypermatter reactor with several times the power of a captive star.
