Solar flares are violent releases of matter and energy within active regions on the Sun.. Flares are identified by a sudden brightening in chromospheric and coronal emissions.. The Sun and the Stars. The Sun and the Stars. Limb darkening. The surface of the sun does not have uniform brightness, it appears bright toward the centre, darker towards the edges, and the colour is redder, an effect known as Limb darkening - why?. Solar Prominence. Sun Fact Sheet. The Sun is a normal G2 star, one of more than 100 billion stars in our galaxy.. . Diameter: . 1,390,000 km. (Earth 12,742 km or nearly 100 times smaller).
