Venus

Venus (or Sol II) was the second planet in the Solar system.

Astronomical data
Originally, Venus was an inhabitable world, geologically comparable to Earth, with an ocean and two continents. (AUDIO: Voyage to Venus, PROSE: Venusian Lullaby) Pollution caused by the Cytherians ruined the planet, causing storms of acid rain. It stayed like this for billions of years, until it was terraformed by human colonists. The terraformed Venus was covered in lush jungles, had an oxygen-rich atmosphere and a mauve sky. (AUDIO: Voyage to Venus)

There were also metal seas on Venus, (TV: "The Singing Sands") and rubies could be found on the planet. (COMIC: Treasure of the Daleks) There was also a mountain range called the Churchill Mountains, which were named after Winston Churchill. (PROSE: Invasion of the Daleks)

By the 27th century, Venus had two artificial moons: Eros and Thanatos. (AUDIO: Venus Mantrap)

Venus had an apparent magnitude of -3.5. In 2009, it was about 26 million miles from Earth. (TV: Partners in Crime)

The mean temperature on Venus's surface was 735 Kelvin and the pressure was 92 times that on Earth's surface. One day lasted 116.75 Earth days. (PROSE: Sunset Over Venus)

Native fauna and flora
There were at least three species of intelligent natives. One was simply known as the Venusians. (PROSE: Venusian Lullaby) Another was known as the Thraskin or Cytherians. (AUDIO: Voyage to Venus) The Wispies also lived on the planet. (PROSE: Sunset Over Venus)

A type of Shanghorn lived on the planet. (TV: The Green Death, PROSE: The War of Art, AUDIO: Voyage to Venus) Other species include the Venusian Night Fish, (PROSE: Doctor Who in an Exciting Adventure with the Daleks) Klakluk (AUDIO: The Paradise of Death), Shrieking Blarosus and the Venusian Sporebeetle. (AUDIO: Voyage to Venus) The Museum of the Last Ones had specimens of extinct species from Venus. (PROSE: The Last Dodo)

In its prime, Venus was covered in dense rainforests, (AUDIO: Voyage to Venus) which were partly made up of Bosifghal and Chedhanhig trees (PROSE: Venusian Lullaby). Venusian spearmint could be harvested from the planet. (TV: The Shakespeare Code) Venusian gulper reached full size mere minutes after the begin of germination. (PROSE: The Secret in Vault 13)

Distant past
Although generally believed uninhabited and uninhabitable by the scientists of 20th and early 21st century Earth, in fact several civilisations called the planet home. (PROSE: Venusian Lullaby, AUDIO: Voyage to Venus)

Circa 3 billion BC, the planet was inhabited by a civilisation known as the Venusians. Despite never becoming space-faring, the Venusian civilisation spanned at least 3 million years, including the Alabaster-Age, the era of the Goldenworkers and the Time of the Gardens. Its major regions and cities included Bikugih, Inarihib, Martahig, Conorihib, Burjianit, Ujannonot, and the High Sweet Lands.

The Doctor and Susan once visited Venus, where they befriended Jilet Mrak-ecado and Jikugihi Dharkhig. (PROSE: Venusian Lullaby) Susan would later recall visiting the metal seas of Venus to Ping-Cho. (TV: Marco Polo)

Decades later, the planet was visited by the First Doctor, Barbara Wright and Ian Chesterton, who were visiting the funeral of Jikugihi Dharkhig. During this time, the sun was getting hotter and making it more and more difficult to live on the surface of the planet. While many Venusians preached acceptance of their inevitable fate, various Anti-Acceptancer factions tried to devise ways of avoiding it, resulting in political conflict.

During the Doctor's visit, the Sou(ou)shi arrived in the skies above Bikugih, where they promised to take the struggling Venusian population to Sol III. In reality, they wanted to consume the flesh of the Venusians. The Sou(ou)shi ship was destroyed when the Anti-Acceptancer faction known as the Volcano People executed their 40,000-year old plan to induce a massive volcanic eruption. The eruption also covered the atmosphere of the planet, which Commander Bismar Mrodtikdhil estimated would give them an extra 5000 years before the end. (PROSE: Venusian Lullaby)

The planet was eventually ruined by the Cytherians, after they accidentally used up all their fossil fuels and produced too much carbon dioxide, causing a runaway greenhouse effect that caused the collapse of their ecosystem. They were forced to escape the planet or preserve themselves for when the planet was inhabitable again. (AUDIO: Voyage to Venus)

Early human era
In the 64 AD, Ian Chesterton pointed out two bright lights in the sky of Earth, Venus and Jupiter. Ancient astronomers couldn't tell the difference between stars and planets, so instead planets such as Venus were referred to as "wandering stars". (PROSE: Byzantium!)

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 II among the first three planets in the solar system to be in immediate danger. (AUDIO: The Satanic Mill)

20th century
In the 1970s, Professor Logan claimed to have planned and executed a manned mission to Venus, but this was exposed as a fraud. (COMIC: Doctor Who and the Rocks from Venus)

Rudolph Steiner devised the Gemini Plan to bring Venus into Earth's orbit, allowing the planet's mineral resources to be economically available. This plan, which would have led to the destruction of Earth, was thwarted by the Third Doctor and Murray Stevens. (COMIC: Gemini Plan)

21st century
The Transit of Venus occurred in 2004. (PROSE: Time Lapse)

In 2009, Wilfred Mott and Donna Noble gazed at Venus from Wilf's telescope in Chiswick at a magnitude of -3.5. Wilf was certain that humanity would get there one day, and that in a hundred years time, they'd be "striding out amongst the stars, jiggling about with all them aliens". (TV: Partners in Crime)

Around the year 2062, the Eighth Doctor and Charley Pollard found Aristede, an artist prepared to crash his craft into the planet as an artistic statement. (PROSE: Venus)

25th century
In the year 2400, when Mars was only just being colonised, Venus had the large city of New Paris and the largest oil reserves after Earth. The Stone family — Mary, Jeff and Andy — were residents. The Daleks invaded the solar system, targeting Venus as a way to outflank Earth and capture the needed oil; New Paris was devastated and the inhabitants enslaved, all bar the Stones who had been in the Churchill Mountains. (COMIC: Invasion of the Daleks, The Oil Well) The moist climate meant the Daleks needed lead paint to avoid rusting, as well as metal roads to travel on. (PROSE: Red for Danger) Guerrilla warfare by the Stones impaired the Dalek occupation (PROSE: Red for Danger, COMIC: The Oil Well) and caused them to depart Venus in their fleet, allowing the Space Army to wipe them out. (PROSE: The Secret of the Mountain)

26th century
