Betelgeuse is estimated to have a diameter 500 to 700 times as large as the sun, or around 6 million miles. This red supergiant star is located in the Orion galaxy.
Although the star is massive in comparison to the sun, the red color implies that it does not burn as hot—its temperature reaches an estimated 6,000 degrees Fahrenheit, versus the sun's at 10,000 degrees Fahrenheit. The supergiant is roughly 520 light-years away from earth but is easily spotted because it burns 7,500 times brighter than the sun. When viewing the Orion galaxy, Betelgeuse can be spotted on its western-most corner. NASA has captured photos of Betelgeuse, which portray the deep red coloring and layers of dust and other objects within its vicinity.
