Pazithi Gallifreya
From Tardis Wiki, the free Doctor Who reference
Pazithi Gallifreya was one of two moons orbiting the Time Lord homeworld of Gallifrey. Its coppery shine was visible even during the day. It was heavily industrialized by the Gallifreyans for smelting purposes.
The moon had the highest amount of Taranium that could be found in the universe. The Time Lords mined it for their temporal technology, such as the Time Scoop.
Ancient Gallifreyans worshipped it as a virgin Goddess. (NA: Cat's Cradle: Time's Crucible)
