15 Saturn has a hexagonal storm

Saturn’s northern hemisphere features a raging six-sided storm nicknamed ‘the hexagon’.

This hexagon, a towering, multilayered storm, has been present on the ringed planet for decades, if not hundreds of years. The strange storm was discovered in the 1980s, but was barely visible until the Cassini mission flew by between 2004 and 2017. Images and data from Cassini reveal the storm to be 300 kilometres (180 miles) tall, 32,000 kilometres (20,000 miles) wide and composed of air moving at about 320 kilometres (200 miles) per hour.
