Päikesekorona, often referred to as the Sun's corona, is the outermost layer of the Sun's atmosphere. It is a vast, tenuous region that extends millions of kilometers into space, far beyond the visible surface of the Sun.

This outer atmosphere is made up of ionized gas, primarily protons and electrons, forming a plasma. The
The corona is visible during a total solar eclipse when the Moon blocks the Sun's bright disk,
