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 is a red supergiant, one of the largest stars known. If Betelgeuse were at the center of our solar system, its radius, â 650 times that of the Sun, would extend between the orbit of Mars and Jupiter.Aldebaran is a red giant of magnitude 0.86 and spectral type K5 III, which means it is orange, tall and it left the main sequence after using all its hydrogen.f Betelgeuse were at the center of our solar system, its radius, â 650 times that of the Sun, would extend between the orbit of Mars and Jupiter.
