Solar flare- explosive release of engery going outward.
Promince-huge loops of relatively cool gas that extends outward from the photosphere thousands of kilometers into. the outer atmosphere.

Explain Kepler's three laws.
Kepler's First Law: Each planet orbits in an ellipse with the sun as the focus.
Kepler's Second Law: As planet moves around its orbit, it sweeps out equal areas at the same time.
Kepler's Third Law: The square of the orbital period is proportional to the cube of the planets average distance from the sun.
