Planet (The Pilot)

While getting away from the sentient oil, the Twelfth Doctor went to a planet located on "the other end of the universe" from Earth to find out how long it would take for the oil to get there.

The TARDIS landed on the planet 23 million years into the future before heading into the past to the Dalek-Movellan War. (TV: The Pilot)
