MERCURY
Planet mercury looks very like our moon. It's about the same size and it's covered in craters, where bits of space rock have crash-landed on it's surface. The biggest crater is the Caloris Basin, which is about 800 miles across. Mercury also has huge plains, rolling hills, deep gorges, chasms, and cliffs.
Mercury is only about a third size of the Earth, but Pluto is even smaller. If you could put them on the scales, it would take 21 Plutos to balance one Mercury.
Mercury is the planet closest to the Sun, but its neighbor Venus is even hotter, because it has clouds to keep in the heat.The surface of Mercury is 662 degree F during the day and -274 during the night.
Mercury doesn't have any weather, because it has no air and hardly any atmosphere. that means there are no clouds to shield the surface of the planet from the baking-hot Sun during thew day, or to keep in the heat night. There is o wind or rain on Mercury, either.
Mercury is the fastest planet. It zooms around the Sun in just 88 days, at an incredible 107,000 mph. That makes faster than any space rocket ever invented.
