Earth

Ravolox was the name used for Earth after the Time Lords transferred the Sol system to another part of Mutter's Spiral at some point prior to the year 2,000,000 (DW: The Mysterious Planet, DW: The Ultimate Foe).

The prophecy of the Vampire Messiah also uses the name Ravolox for Earth. (MA: Goth Opera).

This was at least the second time that the Earth had been forcably relocated; it also occurred in the early 21st century (DW: The Stolen Earth).

Behind the scenes

 * The End of the World, which takes place in the year 5,000,000,000, depicts Earth as once again orbiting its original sun and once again known as Earth, suggesting that at some point the planet was relocated to its original position and given back its original name.
