Behind the scenes

 * Doctor Who: The Time Traveller's Almanac states Clom is located here. As Clom is stated in Love & Monsters to be the twin planet of Raxacoricofallapatorius, it would logically follow that this planet is located in the same galaxy. World War Three, however, has the Ninth Doctor insinuate that Raxacoricofallapatorius is one of 5,000 planets within travelling distance of Earth, implying it's in the same galaxy.
 * This would mean that either the Doctor was mistaken, or the Doctor meant that travelling there was easy.
