Uranus, Neptune is also blue-green in color. The methane in the atmosphere absorbs red light, giving this planet its deep, rich blue color.

Neptune is so far away, it's impossible to see without a telescope. Because Pluto has such a weird orbit, Neptune is actually the furthest planet from the sun for 20 years out of every 248 Earth years. Pluto moved out of the way for Neptune at the end of the 20th century.
