Saturn’s north polar vortex and hexagon in near-infrared false color, imaged by Cassini in 2012 & 2013. The hexagon is believed to be formed by a circumpolar jet stream of 320 km/h (200 mph) winds. Centered on the north pole is a 2,000 kilometer (1,250 mile) wide vortex of 540 km/h (330 mph) winds.
