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.

Our results say Betelgeuse only extends out to two-thirds of that, with a radius 750 times the radius of the sun,” Dr. László Molnár, co-author of the study, said in a statement.

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.

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).

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).

Betelgeuse is at least 10 times closer to Earth and has a mind-boggling radius that would extend to engulf not only all of our inner solar system if it was put in place of the sun, but also ...

Betelgeuse has a sequel — in the form of a companion star that's about the same mass as the sun, orbiting it about once every 2,100 days.

The star is Betelgeuse, a red supergiant in the constellation Orion. The asteroid is 319 Leona, a slowly rotating, oblong space rock in the main asteroid belt between Mars and Jupiter.

Betelgeuse, one of the brightest stars in the sky in the constellation Orion, has long puzzled astronomers due to its history of dimming and brightening, sometimes unexpectedly. Now a new preprint ...
