No, it is a storm, similar to the Great Red Spot on Jupiter.
They are both large, raging storms last for hundreds of years.
It is a giant dust storm like the one that Jupiter has. But Jupiters is a bit bigger. :)
Neptune has a massive anti-cyclonic storm system spanning 13,000 x 6,600 km It is called "The Great Dark Spot". There is also a smaller cyclonic storm in the southern region, called, not surprisingly, "The Small Dark Spot"
Neptune does not have a black hole
to study neptunes dark spot because it has winds that can reach up to 600 mph winds
Neptune's main feature is the Great Dark Spot, a giant storm with winds of over 1000 mph, making it the fastest storm in the Solar System. Neptune also has the Second Dark Spot, a smaller storm with slower wind speeds.
it is thougt to be a hole in the methane cloud
In 1989, Voyager 2 flew by Neptune and photographed a Great Dark Spot about the size of Earth. Like the Great Red Spot on Jupiter, the Great Dark Spot was probably a giant storm. But the storm didn't last long. Images taken fice years later showed that the Great Dark Spot was gone.
It wasn't either really, though it was more similar to a hurricane than to a tornado.
Neptune's winds blow about 2,000 kilometers per hour (1,243 miles perhour) which causes its great dark spot to move around the planet. Neptune's dark spot is a storm which is known to vanish and reform. I surely hop my answers helped you thank you kindly for reading this
About over 20 Earths. Because it is bigger than the Great Red Spot.
Yes it does. The spot is called 'The Great Dark Spot'
