About Betelgeuse
Betelgeuse is a red supergiant of spectral type M1-2 and one of the largest stars visible to the naked eye. It is usually the tenth-brightest star in the night sky and, after Rigel, the second-brightest in the constellation of Orion.
Betelgeuse can be seen through naked eyes. First you want find the Orion Constellation. In Orion Constellation, near the elbow you can see a orange or Deep reddish color star. That is Betelgeuse. The above image represent the image.
Radius: 617.1 million km (887 R☉)
Distance to Earth: 642.5 light years
Surface temperature: 3,500 K
Mass: 2.188 × 10^31 kg (11 M☉)
Coordinates: RA 5h 55m 10s | Dec +7° 24′ 26″
Betelgeuse is easily discernible to even the casual observer, not only because of its brightness and position in the brilliant Orion but also because of its deep reddish colour. The star is approximately 548 light-years from Earth. Betelgeuse is a red supergiant star.
Betelgeuse Dimming

These images, taken with the SPHERE instrument on ESO's Very Large Telescope, show the surface of the red supergiant star Betelgeuse during its unprecedented dimming, which happened in late 2019 and early 2020. The image on the left, taken in January 2019, shows the star at its normal brightness, while the remaining images, from December 2019, January 2020, and March 2020, were all taken when the star's brightness had noticeably dropped, especially in its southern region. The brightness returned to normal in April 2020.

Physical Characteristics:
Betelgeuse is a colossal object — and a very bright one at that. As a red supergiant nearing the final phases of its life cycle, Betelgeuse has an estimated diameter around a thousand times that of the Sun, with an estimated absolute luminosity of 100,000 times the Sun

Mythology:
With the history of astronomy intimately associated with mythology and astrology before the scientific revolution, the red star, like the planet Mars that derives its name from a Roman war god, has been closely associated with the martial archetype of conquest for millennia, and by extension, the motif of death and rebirth. Other cultures have produced different myths. Stephen R. Wilk has proposed the constellation of Orion could have represented the Greek mythological figure Pelops, who had an artificial shoulder of ivory made for him, with Betelgeuse as the shoulder, its color reminiscent of the reddish yellow sheen of ivory.
