Neptune

Neptune

Neptune, the outermost planet in the Solar System, cannot be seen from Earth without a telescope or binoculars. It is covered by icy, bright blue methane clouds that whip around the globe at speeds of more than 700mph (1,100km/h).

Though its diameter is four times that of the Earth's and it is 17 times as massive, it is less dense and doesn't have a solid surface. Eleven moons orbit Neptune, the largest of which is Triton.
