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.
Distance in miles = 3.15 times 10 to the 15th power. That is 315 followed by 13 more zeros! We are 527 light years (a light year is how far light can travel in one year) from Betelgeuse. Each light year is 5.98 trillion miles (10 to the 12th power). Source(s): Just memorized the distance in light years and multiplied by 5.98 trillion. Doug H Â· 7 years ago.
