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. He planned to use the alignment of the planets as a transmitter for the reality bomb, to allow complete destruction of every universe.

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: The Stolen Earth, Journey's End)

Amongst the twenty-seven planets were:
 * Adipose 3
 * Callufrax Minor
 * Clom
 * Earth
 * Flane
 * Io
 * Jahoo
 * Jupiter
 * The Lost Moon of Poosh
 * Pyrovillia
 * Shallacatop
 * Woman Wept

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