A corona (Latin, ' crown ') is an aura of plasma that surrounds the sun and other celestial bodies. The Sun's corona extends millions of kilometres into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph.he sun's corona is much hotter (by a factor from 150 to 450) than the visible surface of the Sun: the photosphere 's average temperature is 5800 kelvin compared to the corona's one to three million kelvin. The corona is 10 â12 times as dense as the photosphere, and so produces about one-millionth as much visible light.
