Mercury is the smallest of all the eight planets of the solar system. The diameter of this planet is 3,030 miles. It is also the closest planet to the Sun.

This temperature swing is the largest of any planet in the solar system. About 4 billion years ago, a huge asteroid slammed into Mercury that created a giant crater about 960 miles.
