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: Speed is relative. In our orbit around the sun: 107,225 kph (66,630 mph). However, the sun is traveling, too, in its orbit around the center of the galaxy. To orbit the sun, we will travel a little faster in January (perihelion) and slower in January (aphelion), but we average 782,460 kph (486,220 mph).
