Betelgeuse's color may have changed from yellow (or possibly orange; i.e. a yellow supergiant) to red in the last few thousand years, based on a 2022 review of historical records. This color change combined with the CMD suggest a mass of 14 M ☉, an age of 14 million year and a distance from 125 to 150 parsecs (~400 to 500 light years). [12]
Based on this size of the stars, astronomers determined Betelgeuse sits just 530 light-years from Earth — about 25% closer than expected. ... However, even at 530 light-years distance, our ...
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] ...
This number is likely much higher, due to the sheer number of stars needed to be surveyed; a star approaching the Solar System 10 million years ago, moving at a typical Sun-relative 20–200 kilometers per second, would be 600–6,000 light-years from the Sun at present day, with millions of stars closer to the Sun.
Astronomers pointed powerful telescopes at the red giant star Betelgeuse, confirming theories that the star had not almost exploded a few years ago, but it did experience a dimming event.

In late 2019 and early 2020, Betelgeuse blew its top. Literally. Around that time the famous bright star marking the right shoulder of Orion suddenly started dimming, dropping to about half its ...
−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.
