Which planet in the Solar System has a great dark spot
Great Dark Spot or possibly through some other unknown mechanisms. However, in 2016 an almost identical spot emerged in Neptune's northern hemisphere. This new spot, called the Northern Great Dark Spot (NGDS), has remained visible for several years. It is unknown whether this spot is still present on the planet, as observations using the Hubble telescope are limited. Great Dark Spot The Great Dark Spot (also known as GDS-89, for Great Dark Spot - 1989) was one of a series of dark spots on Neptune similar in appearance to Jupiter's Great Red Spot. GDS-89 was the first Great Dark Spot on Neptune to
Great Red Spot more than 10°, and was originally based on the average rotational period of the Great Red Spot of 9h 55m 42s. Despite this, however, the spot has "lapped" the planet in System II at least 10 times since the early nineteenth century. Its drift rate has changed dramatically over the years and has been linked to the brightness of the South Equatorial Belt, and the presence or absence of a South Tropical Disturbance. It is not known exactly what causes the Great Red Spot's reddish color. Theories supported by laboratory experiments suppose that the color may be caused by complex
