Uncertainty in the star's surface temperature, diameter, and distance make it difficult to achieve a precise measurement of Betelgeuse's luminosity, but research from 2012 quotes a luminosity of around 126,000 L ☉, assuming a distance of 200 pc. [142]
Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. ... However, even at 530 light-years distance, our planet will still be safe from the eventual explosion.
This is a list of the nearest supergiant stars to Earth, located at a distance of up to 1,100 light-years (340 parsecs) from Earth. ... Betelgeuse: 408 [14] ...
Solar radius is a unit of distance used to express the size of stars in astronomy relative to the Sun. ... Betelgeuse: 764 [10] 531,500,000: Antares A 680 [11 ...
The following well-known stars are listed for the purpose of comparison. Antares (α Scorpii A) 680 [70] AD Fourteenth brightest star in the night sky. [71] Widely recognised as being among the largest known stars. [21] Betelgeuse (α Orionis) 640, [72] 764 +116 −62, [73] 782 ± 55 [74] AD & SEIS Tenth brightest star in the night sky. [71]
Betelgeuse—the star and not the slimy, suit-wearing demon—is one of the most celebrated celestial objects in the night sky. Found in the constellation Orion, Betelgeuse is extremely bright ...
Observing Betelgeuse, which is estimated to be about 10 million years old, allows astronomers to watch what happens late in the lifetime of a star. As Betelgeuse burns through fuel in its core, it ...
Inaccuracies of these measured parameters make determining the true minimum distances of any encountering stars or brown dwarfs fairly difficult. [72] One of the first stars known to approach the Sun particularly close is Gliese 710. The star, whose mass is roughly half that of the Sun, is currently 62 light-years from the Solar System.
