Neptune

The size of Neptune is four times bigger than Earth. The naked eye can never see Neptune from the surface of  Earth because it is too far away from us. The temperature on Neptune's surface is -220° C. Neptune is a distance of 2,796,000,000 miles away from the sun. Neptune has a black spot on its surface, which is a whirlwind, as big as the Earth travelling at 325 metres per second. It takes Neptune nineteen and a half hours to rotate on its axis. It takes Neptune 165 years to orbit the Sun. Therefore one year on Neptune is one hundred and sixty-five Earth years. One day on Neptune is sixteen Earth hours.
