![]() ![]() Many believe that Betelgeuse evolved from an O-type main-sequence star. Formationīetelgeuse is very young in comparison to our Sun, being only eight million years old. It basically consumes one Sun every 10,000 years.īetelgeuse travels through space at supersonic speeds, reaching 30 km / 18.6 mi per second. The star loses around one solar mass every 10,000 years. One AU is the distance between Earth and the Sun! The nebula actually formed out of Betelgeuse’s lost mass. This nebula extends up to 20.000 AU away from the star. It is between 90,000 and 126,000 times more luminous than our Sun however, much of its light is in the invisible part of the spectrum.īetelgeuse has a surface average temperature of only 3,600 K, colder than our Sun, and it is surrounded by a nebula, which is 250 times its size. It is a semiregular variable type of star, having brightness variations from magnitude +0.0 to +1.23. It has exhausted its hydrogen supplies, and in the near future, it will explode as a supernova. Betelgeuse Characteristicsīetelgeuse is a red supergiant star of spectral type M1-M2 la-ab. It is the second brightest star located in the constellation of Orion, the celestial hunter, but since its brightness varies, it often becomes the brightest star in its constellation, outshining Rigel.īetelgeuse is a red supergiant star and its name comes from Arabic, translating to “the arm of the giant,” reffering to Betelgeuses’s position in the constellation, marking Orion’s celestial arm.
