Red Giant Spot
A giant spinning storm in Jupiter’s atmosphere and it is the largest storm in Solar System. This storm has been recorded lasted for more than 300 years. Its size is about twice the size of our Earth. However, it is recorded that the size of the Red Giant Spot shrinking rapidly for quite some time and has been slowing down for recent years.
In 1979, Voyager 1 and 2 spacecraft revealed that the entire system of Red Giant Spot rotates counter-clockwise and takes about six days to complete one rotation. Constantly, it moving across Jupiter’s atmosphere but not at a fixed speed. Since the first recorded observation in the early 1830s, the Red Giant Spot has circled Jupiter at least ten times.
