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)

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)

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)
