What Is the Sun’s Corona? – NASA Space Place

May 20, 2026

The corona extends far out into space. From it comes the solar wind that travels through our solar system. The corona’s temperature causes its particles to move at very high speeds. These speeds are so high that the particles can escape the Sun’s gravity. Conceptual animation (not to scale) showing the Sun’s corona and solar wind.
