Jupiter's winds reach up to 900 miles per hour - three times as fast as those measured during the strongest tornadoes on Earth, a study has found. 'These wind speeds, equivalent to about 900mph, are more than twice the maximum storm speeds reached in Jupiter's Great Red Spot and over three times the wind speed measured on Earth's strongest tornadoes.' For scale, Jupiter's polar winds make devastating Earthly hurricanes look like gentle breezes - with Hurricane Katrina clocking in at 174 mph by comparison. The highest wind speeds of any tornado recorded on earth were just shy of 318 miles per hour which hit Oklahoma, USA in 1999. The molecules left by the comet helped scientists track wind speeds on the gas giant - finding they reach up to 900 miles per hour.
