Jupiter

Jupiter was a gas giant planet located in the Sol system.

History
Prior to the emergence of human civilisation on Earth, a sentient race known as the Jovians evolved on Jupiter. At some point prior to his fifth incarnation, the Doctor visited Jupiter during this era and later told his companions Tegan Jovanka and Turlough that the Jovians had had a beautiful civilisation which had created entirely in their minds. He described the process as being similar to whale song. The Doctor believed that the Jovians had become extinct by the 24th century. (AUDIO: The Jupiter Conjunction)

In the 1970s, English astronaut Guy Crayford was trapped in orbit around Jupiter and rescued by Kraals, who used him as their agent. (TV: The Android Invasion)

At some stage, the Sol system was given a "spring cleaning" which entailed removing most of Jupiter's moons and leaving the largest twelve. (PROSE: To the Slaughter)

Jupiter was eventually colonised by humanity. Following the achievement of independence from Earth, the colonists' government became known as the Jupiter Axis. In 2329, the Axis signed a peace agreement with Earth, ending years of tension between the two powers. In the immediate aftermath of the treaty, the surviving Jovians revealed their existence to humanity. (AUDIO: The Jupiter Conjunction)

The Nerva Beacon was originally in Jupiter's orbit. (AUDIO: Destination: Nerva)

After drifting through space, the asteroid Voga became trapped in Jupiter's gravity and began orbiting it. Humans named the new moon "Neo-Phobus". (TV: Revenge of the Cybermen)

Josiah W. Dogbolter, at one stage, owned Jupiter, as well as Venus and Mars. (COMIC: The Moderator)

The Daleks terraformed Jupiter. (AUDIO: Dalek War: Chapter Two, Dalek War: Chapter Three)

A space station near Jupiter was quarantined by Disinfectodroids. (COMIC: The Germ War)

In the year 4000 Jupiter was one of the key targets for the Dalek takeover of the Solar System. (TV: Mission to the Unknown)

Moons of Jupiter

 * Callisto
 * Voga

Behind the scenes

 * In Revenge of the Cybermen, dialogue states that Jupiter had twelve moons until the arrival of Voga. As discovered later, Jupiter actually has more than sixty. Therefore, the plot of To the Slaughter explains how, further in the future, Jupiter can only have twelve moons.
