A solar wind is a stream of charged particles (i.e., a plasma) which are ejected from the upper atmosphere of a star. When originating from stars other than the Earth's Sun, it is sometimes called a stellar wind.
Definition: solar wind: The wind from the Sun. More specifically, particles, usually electrons and protons, continually streaming away from the corona of the Sun.

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 is the continuous flow of charged particles, ions, electrons and neutrons that comes from the Sun in every direction. The high temperature of the Sun's corona creates a high pressure which causes the particles to be pushed out.
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.

As the solar wind (the flow of charged particles streaming outward from the Sun) impacts a planet at supersonic speeds, it generally forms a bow shock on the sunward side of the planet--that is, a standing wave of plasma that slows down, heats, ...
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.

Solar Wind: The solar wind streams off of the Sun in all directions. The source of the solar wind is the Sun's hot corona, whose temperature is so high that the Sun's gravity cannot hold on to it.
Solar Wind. The outward flux of solar particles and magnetic fields from the Sun. The solar wind is produced primarily in the cooler regions of the corona, known as coronal holes, and flows along the open magnetic field lines.
SOLAR WIND - Supersonic flow of high-speed charged particles continuously blowing off a star (mostly e- and p+). When originating from stars other than the Sun, it is sometimes called a "stellar" wind.

Solar wind is an extension to the Sun's corona. It typically has velocities of 300 - 800 km/s. Plasma densities range from 1 - 10 ions/cc. The ions are about 95% , 4% and 1% heavier components.
Solar wind termination shock The shock caused by the sudden slowing of solar wind as it approaches the heliopause.
Solar Winds
As the Sun burns hydrogen at its core, it releases vast amounts of atomic particles, or pieces of atoms into outer space. These atomic particles, along with the Sun's radiation create a sort of wind, known as the solar wind.

The Earth's magnetosphere consists of a dipole field, similar to that of a bar magnet, and a long tail on the night side produced by the interaction of the solar wind with the Earth's magnetic field.
The boundary marking the edge of the sun's influence where the solar wind and the wind from other stars meet is about 100 and 150 astronomical units from the sun. An astronomical unit (AU)is the distance between the Earth and Sun.
The corona is the seat of the solar wind Prominences are threads of cool gas that lie in the corona and are supported by magnetic fields. (From Stars, J. B. Kaler, Scientific American Library, Freeman, NY, 1992.)

These include the gas tail (also called the ion tail), which is made up of material that is blown straight back by the solar wind. This is generally made of the really lightweight gases.
This barely extant atmosphere includes trace amounts of hydrogen and helium from the solar wind. In 1991, very powerful radio telescopes noticed large sheets of ice contained on the poles, areas unseen by Mariner 10.
The magnetic fields surrounding the planets respond to these fields and particles much of which is supplied by the solar wind.
Many comets have two tails, a gas tail (also called the ion tail) composed of ions blown out of the comet away from the Sun by the solar wind, and a dust tail composed of dust particles liberated from the nucleus as the ices are vaporized.
This radiation was also embedded in strong Solar winds that carried magnetic storms outward from the Sun.

The solar winds push the dust and gas away from the coma causing them to stream off into space to form the comet's tail. The solar winds cause the comet's tail to point away from the Sun.
