... In 1989 there was a space craft called Magellan orbiting Venus in order to map it’s surface. Venus is highly volcanic, lava forms solid waterfalls over much of it’s surface. The time it takes Venus to orbit the sun is 7.5 months to orbit the sun with no moons at all with no moons to follow it . ...

A Short History of Venus
... Venus underwent a runaway greenhouse effect – due to the presence of “greenhouse” gases. As the temperature increased, all of the existing water became vapor, circulated high into the atmosphere. This vapor was split apart by solar UV radiation, the hydrogen released was lost to the planet. Without ...

Terraforming of Venus
The terraforming of Venus is the theoretical process of engineering the global environment of the planet Venus in such a way as to make it suitable for human habitation. Terraforming Venus was first seriously proposed by the astronomer Carl Sagan in 1961, although fictional treatments, such as The Big Rain by Poul Anderson, preceded it. The minimum adjustments to the existing environment of Venus to support human life would require three major changes to the planet. These three changes are closely interrelated, because Venus's extreme temperature is due to the greenhouse effect caused by its dense carbon-dioxide atmosphere:Reducing Venus's surface temperature of 462 °C (864 °F).Eliminating most of the planet's dense 9.2 MPa (91 atm) carbon dioxide and sulfur dioxide atmosphere, via removal or conversion to some other form.Addition of breathable oxygen to the atmosphere.↑
