The Moon

The Moon, also known as Luna, is the largest and, for most of its history, the only natural satellite of the planet Earth. No life exists on the Moon at this present time.

Origins and earliest history
The Moon originated outside of the Sol system; it was originally the moon of the Cthalctose homeworld around 60 million years BCE. At that time it housed the Genesis of Cthalctose which was designed to terraform alien worlds (such as, in the future, Earth) to an environment capable of supporting their species. (NA: Eternity Weeps)

As the Moon originated outside the Sol system, it did not relocate until later in its history. It is therefore unknown whether or not the Moon formed at the same time as the Earth itself. (DW: The Runaway Bride)

Later Pre-history
The Silurians went into hibernation because of the appearance of a "small planet" near Earth, the Silurian home planet at that time, which they believed would devastate their world. (DW: Doctor Who and the Silurians)

20th century
Some time prior to 2001 there was a base on the Moon at Tycho crater. Movements suggesting active life forms further north in the Eratosthenes crater were spotted as early as 1924. (visittorchwood.co.uk)

Humans first reached the Moon in 1969. The Doctor and Martha Jones witnessed the Moon landing several times. (DW: Blink)



By the late 20th century, the Cybermen had established a base on the Dark Side of the Moon. The base served as the staging area for a fleet poised to invade Earth. It also could fire missiles at approaching craft (such as the Doctor's TARDIS which briefly materialised in space nearby). (DW: The Invasion) During the Cyberman invasion of Earth in 1988, the Cyber-Fleet orbited the Moon, waiting for the Cyber-Leader to aquire the Nemesis so that the Fleet may arrive and conquer Earth. The Nemesis, sent to rendezvous with the Fleet, exploded and destroyed the entire fleet. (DW: Silver Nemesis)

In 1992, the Timewyrm created a replica of Victorian-era Cheldon Bonniface on the Moon in order to trap the Doctor. (NA: Timewyrm: Revelation)

Early 21st century
The Moon was, up until (and possibly beyond) the 21st century, considered neutral ground under Galactic Law, meaning that if law-enforcement agents such as the Judoon, who would have broken Galactic Law to conduct their affairs on Earth, had free reign to do so on its satellite. Accordingly, the Royal Hope Hospital was transported from London to the Moon, through the use of an H2O Scoop, by Judoon during their search for a Plasmavore murderer. (DW: Smith and Jones)

In 2009 the Moon nearly collided into the Earth as part of Mr Smith's plan to destroy Earth using Luke Smith's, whose natural power of telekinesis a device named MITRE had amplified. Earth's weather was affected worldwide. However, with Mr Smith "reprogrammed" by a computer virus, Mr Smith had Luke reposition the Moon back into its original orbit. (SJA: The Lost Boy)

Human Moon bases
By the end of the 21st century, Humans had at least one base on the Moon. By 2070, a base housed the Gravitron, a machine for regulating Earth's weather. (DW: The Moonbase). One functioned as a T-Mat relay, co-ordinating T-Mat on Earth (DW: The Seeds of Death).

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

Destruction of the Moon
Circa the 53rd century, the Threshold had established Wormwood, a replica of a late 19th century American frontier town on the Moon as well as the superweapon known as the Eye of Disharmony. When the the Doctor's traveling companions Izzy Sinclair and Feyde sabotaged the Eye of Disharmony, the resulting feedback destroyed the Moon. (DWM: Wormwood).

Other moons
In the time of the Fourth Great and Bountiful Human Empire, the Earth had five moons. A penal colony still existed at this time. (DW: The Long Game, Bad Wolf)

Biological effects
Werewolves, such as the Host, were transformed from their human form into their wolf form whenever they came under the moonlight. The Doctor, through a telescope at Torchwood House, concentrated moonlight into a laser-like beam which killed the Host, saving Queen Victoria of England. (DW: Tooth and Claw)
