Betelgeuse has been a favorite among amateur astronomers for many years. However you pronounce it, its unexpected dimming draws even more attention to this red supergiant variable star in Orion.

Betelgeuse has a radius of approximately 900 times that of our Sun. ... Compare Betelgeuse to other stars of different brightness to determine how bright it is.

Our results say Betelgeuse only extends out to two-thirds of that, with a radius 750 times the radius of the sun." Dr. Molnar continues, "Once we had the physical size of the star, we were able to ...

Found in the constellation Orion, Betelgeuse is extremely bright, especially considering that it’s roughly 650 light-years from Earth (though, it does have a radius 1,000 times bigger than the Sun).
