How far can the solar wind travel?

An object in motion tends to stay in motion, unless an external force applies to it.” Solar wind is produced by the Sun. It is a supersonic stream of particles that usually has a speed within 300–700 km/s, sometimes more. read more

The solar wind blows from the Sun at a gentle 10 km/s or so and then accelerates up to around 800 km/s further out in space. That's a top speed of nearly 3 million kilometres per hour. The exhaust gas produced by a jet engine travels at about 1,300 miles per hour. read more

So, it’s possible that the solar wind may travel farther in these directions. [1] The bubble-like shape of the heliosphere observed by Voyager and Cassini * 1 AU, i.e. astronomical unit, is a distance from Earth to Sun, or about 150 million km. read more
