Sleeper ship/Legends

A sleeper ship was a sublight interstellar vessel whose inhabitants were placed under suspended animation. Typical sublight speeds made trips between stars take centuries, well beyond a normal human lifespan. Thus, sleeper ships were needed for the colonization of other star systems before the invention of hyperspace technology.

Alsakan, Metellos, Axum, and Alderaan were worlds colonized by Humans from Coruscant with this technology.
