Betelgeuse is the star in the left shoulder of the Orion constellation. It is also the name of a character in the movie Beetlejuice.
Betelgeuse is bigger than Aldebaran. Betelgeuse is a red supergiant star, while Aldebaran is an orange giant star. Betelgeuse is one of the largest stars known, with a diameter around 1,000 times larger than the Sun.
No one really knows, because no one has ever been to Betelgeuse. It would take much more time than getting to Pluto.
Betelgeuse is the brighter star compared to Aldebaran. It is a red supergiant star in the constellation Orion and is one of the brightest stars visible in the night sky. Aldebaran is an orange giant star in the constellation Taurus and is not as bright as Betelgeuse.
Rigel is brighter than Betelgeuse. Rigel is a blue supergiant star and one of the brightest stars in the night sky, while Betelgeuse is a red supergiant and although it is one of the largest stars known, it is not as bright as Rigel.
Betelgeuse give off more light than the Sun because it is much larger than the Sun, and the star's core is much larger and more powerful than the Sun's core.
Jupiter is brighter than Betelgeuse in the night sky because it is much closer to the Earth in comparison to Betelgeuse(Betelgeuse is more than 500 lightyears away form the Earth). This way, Jupiter appears larger than Betelgeuse, and celestial objects that appear larger also appear brighter than objects that appear small.
the Betelgeuse is colder than the sun
Yeah, the Suns radiant pressure is more increased then Betelgeuse.
Betelgeuse is one of the larger stars, while Barnard's star is just a little red dwarf star. So, yes- Betelgeuse is far larger than Barnard's.
Yes, the Sun is much smaller than Betelgeuse.
No, Betelgeuse has a lower absolute magnitude compared to the Sun. Betelgeuse is a red supergiant star with a much larger luminosity, making it appear brighter despite its greater distance from Earth.
Rigel appears as bright as Betelgeuse because it is closer to Earth than Betelgeuse, even though Rigel is smaller and less luminous. The brightness of a star is determined by both its luminosity and distance from Earth, so a smaller, closer star can appear just as bright as a larger, more distant one.
