The Moon

The largest natural satellite of Earth, The Moon has a storied history.

History
The Moon was one of Earth's five moons, it being the original one, four more being placed into Earth orbit by the Fourth Great and Bountiful Human Empire (DW: The Long Game). )

History
The specific physical origin is unknown, but it apparently did not form with the Earth. The Silurians reported that it did not appear in Earth's sky until their time. (DW: The Runaway Bride, Doctor Who and the Silurians)

Human bases
By the late 21st century, Humans had at least one base on the Moon. One functioned as a T-Mat relay, co-ordinating T-Mat on Earth (DW: The Seeds of Death),

In 2070, a base housed the Gravitron, a machine for regulating Earth's weather. (DW: The Moonbase).

By 2540, it served as a penal colony for dissidents against the war between Earth's empire and the Draconians. (DW: Frontier in Space)

By the time of the Fourth Great and Bountiful Empire, the Earth had five moons. (DW: The Long Game)


 * We do not know if, by this time, the original natural moon still existed or the nature (artificial or natural) of the moons mentioned in passing.''

Other bases

 * Sometime before the late 20th century, the Cybermen established a base on the dark side of the Moon capable which served as the staging area for a fleet poised to invade Earth. It also could fire missiles as the approaching craft such as the Doctor's TARIDS. (DW: The Invasion)


 * Prior to 2001 the Judoon built a base on the Moon at Tycho crater (visittorchwood.co.uk, DW: Smith and Jones). Movements suggesting active lifeforms were spotted in 1924. (visittorchwood.co.uk)
