How far is betelgeuse from earth in AU's?
Comment: That's a reasonable number, but there's a lot of uncertainty over the exact distance, so it's a bit misleading to give such a precise answer.
Why does a star such as betelgeuse which is located far from earth have a much greater absolute magnitude than apparent magnitude?
well my reason is that the betelgeuse must be very large , because they said that the betelgeuse is located far from earth .

No. Some time in the next million years Betelgeuse will explode as a supernova, but it is too far away from us to damage the earth. All we will see is Betelgeuse getting a lot brighter in the night sky.

Betelgeuse is about 640 light-years from the sun.
By definition, the distance from Sun to Earth is one astronomical unit (AU).
Betelgeuse is a red supergiant star located in the Orion constellation. It is currently thought to be 640 light years from Earth, but it is still unsure. Betelgeuse is one of the largest stars known being as large as 1.6 billion suns! If Betelgeuse were at the center of our solar system, it would extend out as far as Jupiter's orbit.
We will have a pretty sight in the night sky. When it explodes, Betelgeuse is predicted to be almost as bright as a full moon in our night sky for a few weeks. Scientists will also learn a lot about supernovas, from being able to observe one happening relatively close. But, Betelgeuse is too far away to do any damage to Earth.
No, Betelgeuse is too far away to have any effect on the sun.
Because of its ENORMOUS size. We believe that Betelgeuse is about as large as a the orbits of the Asteroid Belt, so if Betelgeuse were here in our own solar system, it would consume Mercury, Venus, Earth and Mars, and probably destroy Jupiter as well. As stars go, the 800 light-year distance to Betelgeuse is not that far away, although we wouldn't want it to be any closer. When Betelgeuse becomes a supernova, it will… Read More
Brightnest is a factor of luminousity and distance as seen from Earth. (Apparent magnitude) Vega - 0.03. Betelgeuse: 0.42 So Betelgeuse is brighter as viewed from Earth.
Betelgeuse is about 1,180 times larger the Sun. So Betelgeuse is about 128,620 times bigger than Earth. So as a rough approximation about 2,127,774,087,928,000 Earths could fit into Betelgeuse. That's 2 quadrillion.
Size-wise, the Sun is to Betelgeuse as the Earth is to the Sun.
Europa is 5.230 AUs from the Sun. Aus are approximately 150,000 million miles, which is the distance from the Earth to the Sun. Au stands for Astronomical Unit
No, Betelgeuse is about 640 light-years from earth, but some stars are many billions of light-years away.
Betelgeuse is approximately 600 light years from Earth.
Betelgeuse is 40,473,416.93376 AU' (Astronomical Units) from Earth.
Studies since 1990 have produced an angular diameter (apparent size) ranging from 0.043 to 0.056 arcseconds.
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.
It's estimated to be about 640 light years away. However there's still a lot of uncertainty over the exact distance.
We haven't sent any spacecraft to Betelgeuse, it is much too far. However, the Hubble Space Telescope has studied Betelgeuse, so I guess that counts.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
About 6.14934346 × 1018 metres
About 262 trillion earths can fit inside Betelgeuse and if Earth were the size of a golf ball, Betelgeuse would be the size of 6 empire state buildings.
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.
Betelgeuse is not located in the solar system. Astronomers have had a lot of trouble trying to measure the distance to Betelgeuse, and their conclusions have varied over a wide range. The best estimate now for the distance to Betelgeuse is 640 light years. That's a little over 40 million times as far from us as the Sun is. Betelgeuse is also interesting in another way ... its size. It may be the largest star… Read More
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 Sirius star is only around 9 light-years away from Earth, while Betelgeuse is around 640 light-years away.
Betelgeuse has an average surface gravity of 0.0023 m/s2 (0.23 cm/s2), which is about 4261 times less than Earth.
two stars are the sun and betelgeuse
Not that far, its just 4hour plane ride.
Betelgeuse is approximately 430 light years away, or a bit over 3.7 million light hours.
About 640 years.
It is around 640 lightyears away.
Betelgeuse is about 391.53 light years from Rigel. Here's a bit of mathematics about working out this distance: The distance ("a") from Earth to Betelgeuse is about 427 light years and the distance ("b") from Earth to Rigel is about 772 light years. The angle between the two stars from Earth is 18.56 degrees. Knowing these three numbers, we can now use the "law of cosines" to calculate the distance (c) between the stars: c… Read More
Polaris is the closest of the three stars.
Any date, less 640 years.
It is the brightest type of star, Red Supergiant.
The star Betelgeuse is estimated to be about 1000 times the diameter of the Sun. If you put Betelgeuse where the Sun is; the planets Mercury, Venus, Earth and Mars would all be inside the star.
Betelgeuse doesn't revolve around the sun. It is a star, even larger than the sun, and much too far away for the sun to have much effect on it.
this means that Betelgeuse, is 3,120,000,000,000,000 Miles from earth perhaps.
Yes, it's one of the brighter stars in the night sky.
jupiter is 15.2 AUs from the sun
Betelgeuse is the brightest star in the constellation Orion However Betelgeuse is a cool red star that is 520 light years from Earth How can Betelgeuse look so bright if it is that far away?
It isn't the brightest star - at least, usually Rigel is brighter. However, Betelgeuse is variable, and can sometimes be brighter than Rigel. Wikipedia lists its luminosity as 105,000 times the luminosity of our Sun; and the distance, as 640 light years. Assuming these numbers, this would make it as bright as a star that is 10.5 times as bright as our Sun, at a distance of only 6.4 light years. In other words, the… Read More
Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time… Read More
Betelgeuse is a good candidate at only 430 light years from Earth is has sufficient mass to explode as a supernova and leave behind a black hole. It has been speculated that Betelgeuse will explode (in astronomical terms) fairly soon.
No, Betelgeuse is a star.
The Earth is 1 AU from the Sun while Mars is 1.52 AU from the Sun so the distance from Earth to Mars varies from 1.52-1 to 1.52+1 AU, which is quite a range. To put AUs into miles multiply by 93,000,000.
Several things to consider: -- Because of its ENORMOUS size. We believe that Betelgeuse is about as large as the orbits of the Asteroid Belt. So if Betelgeuse sat exactly where the sun sits, then Mercury, Venus, the Earth, and Mars would all be inside of it. -- Because it's so close to us. Betelgeuse is roughly 800 light-years from us. That's an enormous distance, but actually pretty close as stars go. -- Because it's… Read More
