Does Betelgeuse have a high or low luminosity?
Betelgeuse typically shows only small brightness changes near to magnitude +0.5, although at its extremes it can become as bright as magnitude 0.0 or as faint as magnitude +1.6.
What is the luminosity of the star Betelgeuse?
about 14,000 Suns
Betelgeuse has a luminosity of about 14,000 Suns at maximum and 7600 Suns at minimum. The peak absolute magnitude of Betelgeuse is about -5.6. The surface temperature is that of a typical M-type red supergiant, about 3100 degrees Kelvin.
Is Betelgeuse a bright or dim star?
Normally, Betelgeuse is one of the ten brightest stars in the night sky. For decades, researchers have known that it undergoes cycles of dimming roughly every 425 days, during which it temporarily loses about one-quarter of its peak brightness.
What type of star is Betelgeuse?
M2Iab
Betelgeuse/Spectral type
How many Earths could fit inside Betelgeuse?
Betelgeuse would engulf all four terrestrial planets — Mercury, Venus, Earth and Mars — and even the gas giant Jupiter. Only Saturn would be beyond its surface….About the Object.

Is Betelgeuse a high mass star?
An example of a high-mass star is the red supergiant Betelgeuse; it is 500 times the size of our Sun. High-mass stars have lives of 10 million years, versus 10 to 50 billion years or more for low-mass stars.
Can a supernova destroy a galaxy?
Supernovas are created during the last moments of a star’s life. These gigantic explosions can wipe out galaxies and the planets inside them. These powerful eruptions are called supernovae. They can emit the same energy in a single instant that our sun will generate in over 1 million years.
How does Betelgeuse compare to the Sun?
Betelgeuse, a red giant, is about 700 times bigger than the sun and about 14,000 times brighter. “We have found stars that are 100 times bigger in diameter than our sun. Truly those stars are enormous,” NASA says on its SpacePlace website. “We have also seen stars that are just a tenth the size of our sun.”.
How big is Betelgeuse compared to Earth?
Between small planets in the solar system and the biggest stars, the size difference is enormous, for example, the diameter of the star Betelgeuse is 141,863 times larger than the diameter of the Earth.
What is Betelgeuse and why will it explode?
Betelgeuse is a red supergiant star in the constellation Orion. It left the main sequence about 1 million years ago, and has been a red supergiant for about 40,000 years. It’s a core-collapse SN II progenitor, which means that eventually, Betelgeuse will burn enough of its hydrogen that its core will collapse and it will explode as a supernova.
Will Betelgeuse go supernova?
Betelgeuse is a bright red supergiant situated in the Orion constellation that could go supernova at any time. Researchers predict that at a distance of around 640 light years away, Betelgeuse could have gone supernova at any time since the 14th century onwards.
