Venus, the second planet from the sun, named after the Roman Goddess of love and beauty. The planet is very similar to Earth in many ways and yet so different. It's about the same size, the same density, the same mass and just about the same gravity as Earth and is classified as a terrestrial planet.
But the big difference is that Venus has a run-away greenhouse effect with a high atmosphere pressure which mainly consists of Carbon Dioxide and Sulfuric Acid clouds. It has the densest atmosphere of our solar systems terrestrial planets.
Venus has an active volcanic surface which shapes the planet. It has many very large volcanos, many which are more than 100 km wide.
