The great Betelgeuse. The stars

Betelgeuse is a bright star that points to the right side of the constellation Orion. Also known as Alpha Orionis, Betelgeuse is a reddish star, one of the brightest in the night sky. It is about 300 light years from Earth.

The diameter of Betelgeuse varies from 419 to 580 million kilometers, which makes it one of the largest stars that can be observed. If Betelgeuse were located in the center of our Solar System, its radius would include the orbits of Mercury, Venus and Earth.
