Mercury is the closest planet to the Sun. It is a barren, rocky planet that looks a lot like Earths moon. The surface of  Mercury is covered with huge holes, or craters, where rocks called meteorites have crashed into it.

The Earth

Life exist on Earth because our planet is just the right distance from the sun for water to be liquid, rather than ice or gas.
