Stolen planets

From Tardis Wiki, the free Doctor Who reference

The Stolen Planets were twenty-six planets and one moon that were taken out of time and space and relocated to the Medusa Cascade by Davros and his new Dalek army for the reality bomb.

All twenty seven planets were returned home by the Doctor, Meta-Crisis Tenth Doctor and Donna Noble. (DW: The Stolen Earth / Journey's End)
