Mercury

A river that runs through New York State and is a drinking source for millions is one of the most polluted in the United States.

Little is known about the surface of the 1st planet in our solar system. One thing we do know, is that when you stand on the day side, the Sun is hot enough to melt lead. That right there is a bad sunburn waiting to happen. But the Messenger spacecraft is now in orbit above Mercury taking photos and giving us a new look at the 1st Rock from the Sun.
