Venus

Venus was the second planet in the Solar 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: "The Singing Sands") Rubies could also be found on Venus. (COMIC: Treasure of the Daleks) There were the Churchill Mountains, 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, Venus 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)

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 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)

(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.
