Question: I would like to know what planet has the biggest storms? ANSWER from Heidi Hammel on May 13, 1996; Right now, the biggest planet -- Jupiter -- holds the record for biggest storms. Jupiter's Great Red Spot, a huge swirling storm system, is bigger than the entire Earth! Saturn, the next largest planet, occasionally has huge storms that are almost as big as Jupiter's Red Spot. But Saturn's big storms, called Great White Spots, usually only last for a few months before they are dispersed by the very strong winds on Saturn. Jupiter's Red Spot has been there for hundreds of years. The Great Dark Spots on Neptune, which come and go on time scales of a few years, are the third largest storm systems in the Solar System.
