Mercury+by+Michael+Simpson

Mercury is made of rock and mineral. The center of Mercury is pure iron. So it's called an iron core.

It has a temperature rate of -284 degrees celcius to 465 degrees above. This is becuse it rotatws very slowly so one side of Mercury is backing (the side thats in the sun) and the other side is freezing cold (the dark side of Mercury).

Mercury is the only near by planet that people have thought to have shrunk causing cliffs 3 miles high to form. Mercury has no moons and it can only be seen through machines because it is right up against the sun.
