Great Spot 1

Similar to Jupiter's Great Red Spot, Neptune has a storm system, dubbed the Great Dark Spot, as large as Earth that rotates counterclockwise in 16 days.


Great Spot 2

In addition to the Great Dark Spot, Neptune has a Dark Spot 2, an almond-shaped storm system, with a shiny core, that takes 16 hours to revolve eastward around the planet. A bright, irregular cloud, called Scooter also zips eastward around Neptune in 16 hours. It appears that Neptune's winds are less turbulent than Jupiter's and thus require less energy to maintain their high velocities.
