200 days - The length of a new record-setting storm on Saturn

The gas giant, our Solar System's sixth planet, endured a storm in its northern hemisphere for over 200 days, breaking a previous record set there in 1903. Large storms are not unusual on Saturn, which is over 750 times bigger than Earth: at its equator upper-atmosphere winds appear to move faster than 1,700 kilometers an hour.
