Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, [24] or 11 Jovian days, as of 2008. Measuring 16,350 km (10,160 mi) in width as of 3 April 2017, the Great Red Spot is 1.3 times the diameter of Earth. [21] The cloud-tops of this storm are about 8 km (5 mi) above the surrounding cloud-tops. [25]
Researchers said on Thursday the Great Red Spot plunges between roughly 200 to 300 miles (350 to 500 km) below the cloud tops on Jupiter, based on microwave and gravity measurements obtained by Juno.
The Great Red Spot, or GRS, is an anticyclone, or a large circulation of winds in Jupiter’s atmosphere that rotates around a central area of high pressure along the planet’s southern ...
A well-known feature of Jupiter is the Great Red Spot, [103] a persistent anticyclonic storm located 22° south of the equator. It was first observed in 1831, [104] and possibly as early as 1665. [105] [106] Images by the Hubble Space Telescope have shown two more "red spots" adjacent to the Great Red Spot.
The so-called "Great Red Spot" is a violent storm, which in the late 1800s was estimated to be about 25,000 miles (about 40,000 km) in diameter – wide enough for three Earths to fit side by side.
Pioneer 11 flew past Jupiter in November and December 1974. During its closest approach, on December 2, it passed 42,828 km (26,612 mi) above the cloud tops. The probe obtained detailed images of the Great Red Spot, transmitted the first images of the immense polar regions, and determined the mass of Jupiter's moon Callisto.

The Great Red Spot (GRS) is a persistent anticyclonic storm, 22° south of Jupiter's equator; observations from Earth establish a minimum storm lifetime of 350 years. [ 83 ] [ 84 ] A storm was described as a "permanent spot" by Gian Domenico Cassini after observing the feature in July 1665 with his instrument-maker Eustachio Divini . [ 85 ]
