Solar wind refers to streaming electrically charged atomic particles that constantly escape from the Sun through coronal holes, which are weak spots in the Sun’s magnetic field.
It is faster and much hotter than Earth’s wind.
Solar wind is traveling at about 1 million miles, 1.6 million km an hour by the time it gets close to Earth.
If it blew on the Earth’s surface, it would obliterate all life, but Earth’s magnetic field and atmosphere protect the planet.
The main difference between solar flares and solar wind is that the flares are localized, abrupt, and massive emissions of radiation and particles, whereas solar wind is constant and relatively less intense.
