It is about half the (left) in the southern hemisphere. It is about half the size as Jupiter's Great Red Spot (about the same diameter as size as Jupiter's Great Red Spot (about the same diameter as Earth). Neptune's winds blew the Great Dark Spot westward at Earth). Neptune's winds blew the Great Dark Spot westward at 300 meters/second (700 mph). Voyager 2 also saw a smaller dark 300 meters/second (700 mph). Voyager 2 also saw a smaller dark spot in the southern hemisphere and a small irregular white cloud spot in the southern hemisphere and a small irregular white cloud that zips around Neptune every 16 hours or so now known as "The that zips around Neptune every 16 hours or so now known as "The Scooter" (right).Scooter" (right).
What we thinkWhat we think
We think that Neptune pulled the outer We think that Neptune pulled the outer planets away from the inner planets planets away from the inner planets so that’s why there is that asteroid so that’s why there is that asteroid space in the middle of the inner space in the middle of the inner planets and the outer planets. planets and the outer planets.
