Stolen planets

The Stolen Planets of the Medusa Cascade were twenty-six planets and one moon, some inhabited, 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 Tenth Doctor, the meta-crisis Doctor, and Donna Noble. (DW: The Stolen Earth / Journey's End)

The Stolen Planets

 * Adipose 3
 * Callufrax Minor
 * Clom
 * Earth
 * Flane
 * Griffoth
 * Jahoo
 * Lost Moon of Poosh
 * Pyrovillia
 * Shallacatop
 * Strepto
 * Woman Wept

''24 planets were taken in 2009, Adipose 3 was taken some time before them, Pyrovillia was taken before 79 AD, and Poosh was taken sometime before the 27th century. Also, Strepto was stolen during the Middle Ages, but the other three were seemingly the only ones taken out of time. This suggests that Strepto was an extra 28th planet, which the Tenth Doctor didn't know of.''
