Stolen planets

The stolen planets transported to 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. (TV: The Stolen Earth) He planned to use the alignment of the planets as a transmitter for the reality bomb, to allow complete destruction of every universe. (TV: Journey's End) Amongst the twenty-seven planets were Earth, Callufrax Minor, Jahoo, Shallacatop, Woman Wept, Pyrovillia, Adipose 3, the Lost Moon of Poosh, Clom, (TV: The Stolen Earth) Flane and Griffoth. (TV: SJAF 1)

All twenty-seven astronomical objects were later returned home by the Tenth Doctor, the meta-crisis Doctor, and Donna Noble, defeating Davros and his plan. (TV: Journey's End)

Behind the scenes
The non-narrative Doctor Who: The Time Traveller's Almanac refers to the planets Strepto, which in the novel 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 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.
