Venus, Earth's closest planetary neighbor, is similar in size but vastly different in other aspects. It has a dense atmosphere primarily composed of carbon dioxide, nitrogen, and sulfuric acid, leading to constant cloud cover. The thick clouds trap heat, creating a greenhouse effect with temperatures exceeding 480°C. Despite several spacecraft landing attempts, the extreme heat causes them to burn up quickly. Venus's surface is marked by canyons, craters, plains, and active volcanoes. Interestingly, a day on Venus is longer than a year, taking 8 Earth months to rotate on its axis while only 7 months to orbit the Sun.
