Nope. This is Neptune, the solar system's fourth largest planet in diameter. It
was first seen in 1846 and has only been visited by one spacecraft, Voyager 2,
in 1989. The planet is probably made up of a combination of ice and rock. Its
blue color results from absorption of red light by atmospheric methane.
