Moon

A moon (also known as a natural satellite) was an astronomical object found in orbit around a planet.

You may be looking for Earth's moon or Doctor Moon.

Some moons, like Voga, were planetoids brought into orbit around a planet by the planet's gravity, while others were the result of a collision between objects during the formation of a solar system. (TV: Revenge of the Cybermen ^[+]Loading...["Revenge of the Cybermen (TV story)"])

Across its history, Gallifrey had at least three moons. An unnamed satellite, the heavily industrialised Pazithi Gallifreya (COMIC: Agent Provocateur ^[+]Loading...["Agent Provocateur (comic story)"]) and the lost moon, Botoya. Built into the latter was a device that could rewrite history on a grand scale, which was why the Doctor suspected the ancients of Gallifrey had hidden the moon. Botoya subsequently became a legend in Gallifreyan culture, one not widely believed in. (AUDIO: The End of the Beginning ^[+]Loading...["The End of the Beginning (audio story)"])
