Tiaanamat
From Tardis Wiki, the free Doctor Who reference
Tiaaanamat was a large inhabited asteroid, orbiting the planet Akhaten. The asteroid; the largest of the planet's rings, was composed of molten magma ore and visited primarily by species from the neighbouring seven planets.
Tiaaanamat also played host to the famous Festival of Offerings, a millennial choral ceremony held when the planet's rings aligned that attracted pilgrims from far and wide.
The Eleventh Doctor and Clara Oswald visited the vast, winding markets of Tiaaanamat, as he had done previously in his first incarnation with his granddaughter.
