Solar wind
The solar wind is a stream of charged particles ejected from the upper atmosphere of the Sun. It mostly consists of electrons and protons with energies usually between 1.5 and 10 keV. The stream of particles varies in temperature and speed over time. These particles can escape the Sun's gravity because of their high kinetic energy and the high temperature of the corona.

Solar wind
A steady stream of charged particles that boil off the sun's outer atmosphere and which stream away along magnetic field lines which lead into the interplanetary medium. It is composed of charged particles such as protons , electrons and helium nuclei. When these particles become trapped in the Earth's magnetic field they can cause aurorae when they stream down to earth at the magnetic poles and optically excite atoms and molecules in the upper atmosphere.
