Segonax
From Tardis Wiki, the free Doctor Who reference
Segonax was a dusty, arid desert planet with a blue atmosphere. A large, magenta-pink ringed planet was seen in Segonax's skyline. There was little plant life, animal life, or water on the planet, but it was not without a stable ecosystem or life, including the native Segonaxians. The Psychic Circus was based on Segonax for some time (certainly as long as the Gods of Ragnarok still had influence over it). (TV: The Greatest Show in the Galaxy)
