Habitable No, too hot

Venus is the second planet from the Sun, which orbits around the Sun every 224 earth days. The planet is named after the Roman goddess Venus, of love and beauty. After the Moon, it is the brightest object in the night sky.

Venus is a terrestrial planet. Venus is sometimes called Earth's 'sister planet', because of the similar gravity, size, and bulk composition. Venus is also the closest planet to Earth. Electrical lightning storms may also occur on Venus like Earth. However, Venus is very different from Earth in many ways. It has the densest atmosphere of all of the terrestrial planets, consisted of more then 96.5% of carbon dioxide. The atmospheric pressure is also 92 times more dense then Earth's.

Venus has a mean temperature of 735 K (863 °F, 462 °C) on it's surface, making it the hottest planet in the Solar System by far. Venus also might have had oceans like Earth in the past, however these have been vaporized due to the runaway greenhouse effect, which causes the high temperatures of Venus.

Venus characteristicsEdit

As Venus is a terrestrial planet, it has a rocky body like Earth. In size and mass, the planet is very similar to Earth, and is often called Earth's 'twin', or 'sister', and sometimes 'hellish twin'. The diameter of Venus is 12,092 km, only 650 km less than Earth's. It's mass is around 81.5% of Earth's. Weather conditions are extremely different then Earth's but do have similarities. For instance, Venus may have thunderstorms, like Earth. Rain also falls. Unlike Earth's normal rain however, Venus's rain consists of sulfuric acid, and this only occurs in the upper atmosphere. Venus has clouds like Earth, however these thick clouds consist of sulfur dioxide. Venus also has Snow, like Earth, although it is very different from Earth's, as it seemingly is able to survive in severely hot temperatures. However since this only occurs in the upper Venus mountains, the Venus mountains might be extremely cold, generating earth-like snow.

The CO2-rich atmosphere along with the thick sulfur dioxide clouds generate this extremely strong greenhouse effect.

Venus is often described as a 'hellish twin of Earth'.
