Mercury (planet)

Mercury was an inner planet in the solar system. The temperatures on Mercury were hot enough to melt lead and there was very little atmosphere.

At one point, Mercury was used as a waste dump, but its orbit was accidentally destabilised and it plunged into the sun. (PROSE: To the Slaughter) The Eighth Doctor once claimed that Mercury had "very little atmosphere" after dumping a vampire on the planet. (AUDIO: Situation Vacant)

Observing a temporary chronological disturbance based on a sudden instability in Sol in 1639 caused by the Eleven's stolen stellar manipulator, the Time Lords noted Sol I among the first three planets in the solar system to be in immediate danger. (AUDIO: The Satanic Mill)

When asked about her holiday experiences, Donna Noble listed Mercury among the locations which she had visited. (COMIC: The Widow's Curse)

The Eleventh Doctor, with Amy Pond and Rory Williams, visited Mercury in the 367th century and witnessed the first contact between human miners and the native Mercurian energy beast. (COMIC: Hot Stuff!)
