Unlike Uranus, Neptune sometimes exhibits a dark spot known as âthe great dark spot.â The 8,000 mile long spot, which resembles Jupiterâs Great Red Spot, is a huge area of storm activity that is thought to represent a hole in Neptuneâs methane cloud. Unlike Jupiterâs spot, however, the great dark spot seems to have a much shorter life-span and is cloud-free in the middle. There have been several of these spots that have come and gone on Neptune since 1989. Winds in excess of 1,500 miles per hour have been recorded within the spot, making it the solar systemâs windiest place.

If you wanted to write it out, it would be 102,000,000,000,000,000,000,000,000 kg. Neptune has 17 times as much mass compared to the Earth.
