Stolen planets

The Stolen Planets of the Medusa Cascade were twenty-six planets and one moon, some inhabited, some not, that were taken out of time and space and relocated to the Medusa Cascade by Davros and his New Dalek Empire for the reality bomb.

All twenty-six planets, and the one moon, were returned home by the Tenth Doctor, the meta-crisis Doctor, and Donna Noble. (DW: The Stolen Earth / Journey's End)

Behind the scenes
The non-narrative source REF: Doctor Who: The Time Traveller's Almanac refers to the planets Strepto, which in TWN: Something in the Water, was said to have vanished around the Middle Ages, and Griffoth as being taken by the Daleks. Strepto's disappearance is contradicted by DW: The Stolen Earth, which counts 24 planets being taken from 2009 and the remaining three from other eras named by the Tenth Doctor and Donna as the Lost Moon of Poosh, Pyrovillia and Adipose 3, causing the Shadow Proclamation's map to put the planets in alignment.
