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.
The Star Betelgeuse is a red supergiant star of spectral and luminosity type M1-2 Ib. The star may have between 12 and 17 times Sol's mass (ESA), over 650 times Sol's diameter, and around 40,000 to 100,000 times its bolometric luminosity.etelgeuse is the bright, orange-colored star in Constellation Orion, at top left (another image with enhanced colors). Like many of the stars of Orion, it was probably formed a few million years ago from the molecular clouds observed in Orion but has evolved rapidly due to its unusually high mass.
