The Sun is the star at the center of the Solar System. It is the brightest regularly visible celestial body in Earth's sky, the second being the Moon.
Sunlight is one of the basic weaknesses of all vampires, including the Originals, having been a key ingredient in their creation. As there is no Sun and Moon Curse, vampires are naturally weak against the sun.
