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.
Stars of the constellation by distance (red-green 3D view) and the brightness of each star (star size) Bright stars Betelgeuse , also designated Alpha Orionis, is a massive M-type red supergiant star nearing the end of its life.
Solar radius is a unit of distance used to express the size of stars in astronomy relative to the ... Betelgeuse: 764 [10] 531,500,000: Antares A 680 [11] 473,076,000 ...

−119 [d] or ~R Betelgeuse: L/T eff & AD Widely recognised as being among the largest known stars. [21] Might be the largest star visible to the naked eye. [30] The higher radii estimate assume Mu Cephei is in the Cepheus OB2 OB association. [28] [31] Other sources suggest Mu Cephei and Betelgeuse are likely similar in properties.
The dimming of Betelgeuse seen at the end of 2019 and the start of 2020 explained — the red giant star “sneezed.” Betelgeuse dimmed in the final few months of 2019, perplexing both ...
Betelgeuse has entered an uncommon period of brightening again, this time rising in brightness by around 50 percent. Is the star about to go supernova? Betelgeuse Is Being Weird Again
