The solar wind is a stream of charged particles (i.e., a plasma) which are ejected from the upper atmosphere of the sun.
The Solar Wind
"Plumes" of outward flowing, hot gas in the Sun's atmosphere may be one source of the solar "wind" of charged particles.
Solar wind (stream of particles from the Sun) is usually around 0.001 joules per square meter per second -- about a million times less than sunlight.

It takes the solar wind about 4.5 days to reach Earth; it has a velocity of about 250 miles/sec (400 km/sec). Since the particles are emitted from the Sun as the Sun rotates, the solar wind blows in a pinwheel pattern through the solar system.
