Jupiter's South Pole


The South Pole of Jupiter was first photographed in detail by the Juno spacecraft, which arrived at Jupiter in July 2016 and entered a polar orbit. In the images it returned, six cyclones were discovered at the planet's south pole: one in the center and five around it, with their centers approximately forming a regular pentagon. Each cyclone was about in diameter, with a wind speed of about. All of them were rotating clockwise. A similar picture at the North Pole of Jupiter presents nine cyclones of similar size: one in the center, and eight around it, rotating counterclockwise.
Before Juno, only the Galileo probe had orbited Jupiter, from 1995 to 2003; however, its orbital inclination made it impossible to observe the polar regions of Jupiter; Cassini, which flew past Jupiter in 2000, also had no opportunity to photograph the polar regions. Thus, they remained largely unknown until 2016 ; however, in 2000, the polar X-ray spots of Jupiter were detected.
Jupiter's geographic south pole is also the location of its magnetic South Pole.
