text: The closest planet to Earth in density, size, and sometimes distance also is, in fact, Venus. It was even once may have been known as the most Earth-like planet in our solar system. Venus and Earth has come similar features such as rocky sediment, valleys, mountains, and craters. However, Venus isn't all that pretty. There are some really big dangers when coming in contact with this planet. Venus has almost a 97 percent carbon dioxide blanket that covers the planet. The fluffy clouds are really just sulfuric acid in the atmosphere on Venus. The temperature on Venus is an average of 800 degrees Farenheit and the atmospheric pressure is 90 times greater than what we experience here on Earth. Because of these harsh conditions the several missions to Venus were remain unknown because no spacecraft was able to survuve the landing for more than a few hours leading to us not being able to collect samples of the materials on Venus's surface.
