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.The word corona is a Latin word meaning crown, from the Ancient Greek ÎºÎ¿ÏÏÎ½Î· (korÅnÄ, âgarland, wreathâ).The high temperature of the Sun's corona gives it unusual spectral features, which led some in the 19th century to suggest that it contained a previously unknown element,  coronium .he Coulomb logarithm is roughly 20 in the corona, with a mean temperature of 1 MK and a density of 10 15 particles/m 3, and about 10 in the chromosphere, where the temperature is approximately 10kK and the particle density is of the order of 10 18 particles/m 3, and in practice it can be assumed constant.
