Planet (Listen)

This barren unnamed planet was thought to be the very last planet left at the End of the universe.

Astronomical data
The planet's surface was rocky and desolate with a spiked, reddish, mountainous terrain and a pink and scarlet sky, dwarfed by an enormous, expanding Sun. The planet's atmosphere was oxygen rich and apparently breathable for humans.

History
Believed be the last planet in existence at the end of the universe, by this time the planet's only inhabitant was human time travel pioneer, Orson Pink, whose time shuttle had crash landed following an experimental timeshot from the 22nd Century. Pink was reluctant to leave the capsule and venture onto the planet's surface, fearful of an unknown entity he believed existed beyond the airlock.

The Twelfth Doctor and Clara Oswald landed on the planet towards the end of its life, searching for a mysterious, camouflaged creature. (Listen (TV story))
