As an early M-type supergiant, Betelgeuse is one of the largest, most luminous and yet one of the most ethereal stars known. A radius of 5.5 AU is roughly 7003118000000000000â 1180 times the radius of the Sunâable to contain over 2 quadrillion Earths (2.15 Ã 1015) or more than 1.6 billion (1.65 Ã 109) Suns.
Betelgeuse has around a thousand times the radius of the sun, if it was placed in the center of our solar system the star would reach beyond the orbit of Jupiter! Betelgeuse is estimated to have a maximum mass of around 20 to 30 times that of the sun. Betelgeuse is estimated to have surface temperatures of around 3200C (5800F), around 60% as hot as the sun. Due to its enormous size Betelgeuse is around 100,000 times more luminous than the sun. Infrared image of Betelgeuse, the two white areas are hotspots on the star's surface.
