Mercury By Sharon Fabian

---

¹     Mercury is an extreme planet. It is the fastest of all the planets. It is one of the hottest planets, and it is also one of the coldest! It may be the site of the largest crash in the history of the solar system. Mercury may also have the strangest view of the sun in the whole solar system!
 
²     Mercury zooms around the sun at a speed of about 48 kilometers per second; the Earth travels at a speed of about 30 kilometers per second.
 
³     At certain times and places, Mercury's surface temperature can rise to twice the temperature inside an oven when you are baking a cake. On the other hand, in the shadow of its north pole's craters, Mercury has ice like our north pole does.
