  3. Mercury At midday it is hotter than an oven – about 350 degrees celsius. But at night it is freezing cold, because the planet has no atmosphere to keep the heat in. The USA mariner 10 spacecraft sent back pictures of Mercury in 1974-75.

  4. Its craters were formed when the young planet was bombarded by space rockets and its plains were formed when lava flooded the surface. Only one space probe Mariner 10 has visited Mercury so far. It flew by the planet three times in 1974-75. Astronomers are now set to return. The United States Messenger probe flew by in 2008 and in 2009 and a European probe called Bept Colombo will be launched in 2012
