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.
Best Answer: ~33 km/s or 120,000 kph But, the sun is orbiting the Milky Way at 220 km/s. Yet the absolute velocity of the solar system is ~320 km/s. So you really are traveling one onethousandth of the speed of light!
