All about Mercury

No, I am not talking about the element. I am talking about the planet! Mercury is the planet closest to the sun and the smallest planet. It has a very thin atmosphere. This makes its temperatures vary a lot. The side that is facing the sun is extremely hot, with temperature 427 Celsius (801 Fahrenheit) and the other side is freezing, up to -173 Celsius! (-279 Fahrenheit) One year on mercury is only 88 Earth days! Its radius is only 2440 kilometers. NASA's MESSENGER flew by Mercury in 2008 and gave us stunning pictures of it. Mercury is kind of like our moon, with a lot of crater holes.
Mercury is named after the messenger of the Roman gods. In Greek mythology, the messenger of the gods is called Hermes. He has winged shoes for fast transportation.
 Mercury is made up of mostly iron.
