The solar wind speed at Earth normally lies around 300km/sec but increases when a coronal hole high speed stream (CH HSS) or coronal mass ejection (CME) arrives. During a coronal mass ejection impact, the solar wind speed can jump suddenly to 500, or even more than 1000km/sec.
Like Jupiter, Saturnâs atmosphere is composed mostly of hydrogen. Wind speeds can reach as high as 1609 km/h (1000 mph) which is just about as fast as a speeding bullet. The highest wind speed ever recorded on Earth during a hurricane was in 1996, during Tropical Cyclone Cynthia when gusts reached 408 km/h (253 mph).
