Betelgeuse and Rigel - David Rives

Betelgeuse and Rigel are the brightest stars in the constellation Orion. They are easily seen above and below the famous belt and sword.

Betelgeuse, the 9th brightest star in the sky, is a red supergiant. As one of the largest known stars, Betelgeuse is truly a giant - 14 times more massive than our sun and 800 times its diameter. Betelgeuse is so large that it could contain over 1 and a half billion of our suns. If placed in the center of our solar system, the outer surface of Betelgeuse would extend almost to the orbit of Jupiter - engulfing Mercury, Venus, Mars and the Earth.
