Sun - The Solar Wind

space

The end of the corona marks the last of the Sun's strong magnetic field regions. photons race into empty space.

There are also swarms of particles. There are only a few per cubic centimeter—an almost perfect vacuum. They are all part of the solar wind, a continuous stream of matter flowing away from the sun. Slowly, the Sun is losing material to space. The rate of this loss is very small, so it will not seriously affect the Sun's evolution. (Some stars, however, have powerful winds that can carry off a substantial fraction of their mass.) The solar wind permeates the entire solar system, and beyond.
