Venus is one of the hottest planets in the Solar system. The temperature on its surface is 482 degrees. This unfriendly place looks much the same as the Earth 4 billion years ago. Both planets were formed from the same gas cloud but Venus lost most of its water and atmosphere. This happened because the planet turns very slowly. As a result, now it has no magnetic field to protect it from the Sun's winds. The planet has turned into a lifeless desert. Most space modules that were sent to Venus, could not work on the planet more than two hours. The acidic clouds and high pressure quickly made them absolutely useless.
