Venus

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

Astronomical data
Originally, Venus was an inhabitable world, geologically comparable to Earth. (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: Marco Polo) Rubies could also be found on Venus. (COMIC: Treasure of the Daleks) There were the Churchill Mountains, named after Winston Churchill. (PROSE: The Dalek Book)

By the 27th century, Venus had 2 artificial moons; Eros and Thanatos. (AUDIO: Venus Mantrap)

Venus had an apparent magnitude of -3.5. (TV: Partners in Crime)

Native fauna
There were at least two species of intelligent natives. One was simply known as the Venusians. (PROSE: Venusian Lullaby) The other was known as the Thraskin or Cytherians. (AUDIO: Voyage to 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 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)

At its prime, Venus was covered in dense rainforests. (AUDIO: Voyage to Venus) Venusian spearmint could be harvested from the planet. (TV: The Shakespeare Code) Flowers were also found on the planet, some of which survived until the colonisation by humans. (TV: The Wheel in Space)

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. (TV: The Wheel in Space)

Circa 3 billion BC, the planet had a civilisation. (PROSE: Venusian Lullaby) The planet was 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)

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)

21st century
During Zoe Heriot's time, human scientists found flowers living on the planet. Space Station W3 had some aboard. (TV: The Wheel in Space)

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)

By 2075, there was a human colony on Venus. Captain Anastas Thrax and his space pirates hijacked supply ships en route there until he was defeated by the First Doctor, John and Gillian. (COMIC: The Hijackers of Thrax)

In an unspecified year, 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) Guerilla 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)

24th century
Venus was used as a rubbish dump for a time. Humans tried to terraform the planet and the whole atmosphere boiled away into space. (PROSE: To the Slaughter)

Later history
Long after Earth was barren and lifeless, another group of humans came to Venus and colonised it by modifying themselves. They later called themselves Venusians. Empress Vulpina awoke the Cytherians and after a brief conflict, the Venusians and Cytherians were able to live in peace. (AUDIO: Voyage to Venus)
