I am not really that sure ,but i think that it is hydrogen and heluim considering that its a red giant
Brightnest is a factor of luminousity and distance as seen from Earth. (Apparent magnitude) Vega - 0.03. Betelgeuse: 0.42So Betelgeuse is brighter as viewed from Earth.
A star's brightness is a function of its luminosity, or the amount of energy it produces per unit time. Vega must have a higher luminosity, meaning it fuses more material than Betelgeuse in a given period of time.
Yes, it is. Despite being 640 or so light years away from us, it is still one of the brightest stars in our sky, because of its huge size and luminosity.
Betelgeuse is the reddish star on the top of the constellation.
The star Betelgeuse is a supergiant.
Betelgeuse belongs in the constellation of Orion
Betelgeuse is probably older, but it's hard to give exact ages for stars. Both of them are only a few million years old, much younger than our 4 billion year old sun. See related questions for more details on the ages of those stars.
No, Betelgeuse has already past that stage and has become a redsupergiant.
Of the stars listed, Alpha Centauri is the nearest star to Earth. But there is one closer; Proxima Centauri is a tiny, dim red dwarf star; "near" Alpha Centauri only by astronomical standards, it is still 3 light MONTHS away. But that's still 3 light months closer to the Sun.
No. Far from it. Polaris, also called the North Star and the Pole Star, is the one situated within about 2/3 of a degree of the North Celestial Pole.
No, Betelgeuse is a red giant star.
Sirius and Betelgeuse are two of the brightest stars in the night sky, with Sirius being the brightest and Betelgeuse being the 9th brightest. Betelgeuse is in the wonderful constellation of Orion. Sirius is in the nearby constellation of Canis Major. They are very easy to spot, with...
Betelgeuse or Alpha Orionis and Rigel or Beta Orionis are in the constellation of Orion the Hunter.
Betelgeuse or alpha Orionis makes up part of the constellation Orion.
It was probably formed, like other stars, by the gravitational collapse of a "stellar nebula". Betelgeuse is an old star now, a red "supergiant". It would have been very different originally, of course.
The same as all stars, hydrogen.
The red colour means that it's surface temperature is cool < 3,700K. At that temperature, the spectrum of light is red.
Most definitely. Jupiter is a planet and Betelgeuse is a star. Our sun is much larger than Jupiter and Betelgeuse is much larger than our sun.
Quite simply because Rigel is still on the main sequence whereas Betelgeuse has come off the main sequence and is only fusing helium in it's core, whereas Rigel is still fusing hydrogen in it's core. This is the reason for the difference in temperature.
The position of Betelgeuse in the sky is a function of the date and your location. I recommend the open-source planetarium program "Stellarium", which will tell you, for any location and date you specify, the location of any star or planet in the sky.
Betelgeuse is the eighth brightest star in the night sky and the second brightest star in the constellation of Orin. It is classified as a Red Giant. Astronomers believe that Betelgeuse is only 10 million years old, but has evolved rapidly due to its high mass. Betelgeuse is made from: Helium,...
Probably Uggghhhh the Caveman. Betelgeuse is one of the brightest stars in the night sky; we can see it clearly even in our light-polluted urban skies. In the pitch darkness of a primitive night without any light except the campfire, it would have stood out like a beacon.
The word "Betelgeuse" has 3 syllables in it Be-tel-geuse.
If your living north of the equator then you can see it most nights above and to the left of Orion's Belt (three stars in a row)
Betelgeuse is red because of it's temperature. This color is because Betelgeuse is a red giant star that has used up it's hydrogen fuel so now the star is expanding as it cools and within a few million years will shed it's atmosphere and become a white dwarf star. See related question for more...
Betelgeuse is much bigger, in size than Rigel - about 12 times. but only just smaller in terms of mass. Betelgeuse has a radius of about 936 times that of our SunRigel has a radius of about 78 times that of our SunBetelgeuse has a mass of 18 times that of our SunRigel has a mass of 17 times that of...
The circumference of Betelgeuse is about 1180 times the circumference of our sun.
Betelgeuse is a red super giant, relatively luminous, and one of the largest stars known. For comparison, if the star were at the center of our solar system its surface might extend out to between the orbits of Mars and Jupiter, wholly engulfing Mercury, Venus, Earth and Mars. Astronomers believe...
No, it's a star in the Orion constellation
Because our Sun is a lot closer. 93 million miles instead of 3.7 quadrillion. (3,762,239,880,000,000 miles)
Betelgeuse ("beetlejuice") is believed to be only a few million years old (~ 8.5 million) due to it's high mass. It is also believed, that it may become a supernova within a time frame where it could be observed by human civilization.
No. Betelgeuse does not affect us.
With a radius of 1180 times the size of our sun, Betelgeuse has a volume of 1.64 billion times the volume of our sun.
It is hard to know for sure but it is thought to be about 3500°C or 6332°F.
Betelgeuse has been bright in the night sky for millions of years. It would have been observed from the earliest days and therefore cannot have a discoverer.
Like most bright stars, humans have been able to see Betelgeuse for as long as humans have been around, so nobody could be said to have discovered it.
No. Betelgeuse is large and bright, but not largest or brightest.
Betelguese is large enough to undergo a supernova explosion at the end of it's life. Whats left after that explosion could be a white dwarf, a neutron star, or even a black hole. As large as Betelguese is, it's expected to create a black hole.
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.
One parsec is equivalent to 3.3 light years. 150 parsecs = 150 x 3.3 = 495 light years
Betelgeuse is the bright red giant star at the left shoulder of Orion the Hunter.
No, it is a red supergiant star.
Betelgeuse is around 10 times greater in diameter than Rigel.
RA 5h 55min, DEC 7 deg 24 in 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...
All elements up to Iron are found in very star (except for very young stars as they have not reached that point yet). Though most of the elements are hydrogen and helium.
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...
Every star is pretty huge, compared to anything in our life experience. In size. .
Betelgeuse: Red giant. Diameter 1,180 solar radii. .
Aldebaran: Orange giant: 45 solar radii. .
Alpha Centauri - Which one? A, B or C. For A, yellow dwarf: 1.22 solar radii. .
Polaris: Which one? A, Ab, B ...
I saw it last night. Betelgeuse is one of the brightest stars in the sky, you just need to know where to look and it's easy to see.
Some time in the next million years, probably. That's a very short time for stars, but a long time for humans to wait. Astronomers are still studying it to try to make a more accurate prediction.
Rigel is a lot hotter than Betelgeuse. Rigel - 11,000K Betelgeuse 3,500K
The absolute magnitude of Betelgeuse is -6.05
Betelgeuse is much larger than Rigel.
No, Betelgeuse is huge not huger than Antares. Its about 30 times bigger than the sun!
Yes, Betelgeuse is a red supergiant star.
Yes. It's very prominent ... one of the brightest and reddest visible stars. Learn to identify the constellation of Orion. Betelgeuse marks the hunter's "right shoulder". See related link for a star map.
Betelgeuse is much larger than Rigel. Betelgeuse has a radius about 15 times the radius of Rigel, and a volume of about 3500 times Rigel.
No it isn't. If you want to find it , it is in the Midwestern sky and is diagonally left above the constellation Orion'.
Betelgeuse is in the constellation Orion and is best seen during the winter months in the northern hemisphere. It is very well placed for viewing around the months of November, December and January. Orion is a very easy constellation to find and Betelgeuse is the very bright and reddish looking star...
Rigel and Betelgeuse don't orbit each other. They are hundreds of light-years away from each other.
Yeah, the Suns radiant pressure is more increased then Betelgeuse.
Its between 500 to 790 light years away, but it has been proven difficult to measure. 644 light years is the approximation.
about 650 times the diameter of the sun the sun is 1.392.000 km big but the star appears tho chance its shape now and then so the size differs a bit every one and a while. that`s what the say on wikipedia at least
Antares has a radius of about 800 solar radii.Betelgeuse has a radius of about 1,180 solar radii. See related link for a pictorial of the difference.
Yes, it is a "red giant" star. You can see it quite easily in the evening in this season (early winter in the northern hemisphere); it is the bright red star at the shoulder of Orion the Hunter.
Alpha Centauri: No .
Antares: No .
Polaris: Yes .
Alpha Orionis (α Orionis, α Ori)
Betelgeuse is a star, not a constellation. It is part of the constellation Orion, the hunter.
You could see it last year. Betelgeuse is one of the brightest stars in the sky, and has been for a long time.
Both Betelgeuse and Pollux are close to the end of their life. Both of the stars are large and cold in surface temperature. One difference is that Betelgeuse is a red supergiant, and Pollux is an orange giant.
Betelgeuse is more luminous than Aldebaran.
Betelgeuse is a star, so there is little chance that anyone lives on it.
No, Betelgeuse is too far away to have any effect on the sun.
There are many red super giant stars.The most noted in the Northern hemisphere is Betelgeuse, the top left star in the constellation Orion.
Rigel is blue and Betelgeuse is red.
The radius of Betelgeuse is 1180 times the radius of our sun.
If Betelgeuse (beetle juice) exploded then we would experience a supernova. actually Betelgeuse already had it's supernova. It's predicted that earth may see the supernova in around 2012-2013 around that year. Editing Correction: You can't detect a star going supernova before the light has reached...
No. Currently UY Scuti is the star estimated to be the biggest, but we are not very sure of their size; beside UY Scuti, VY Canis Majoris and a few other stars are also larger than Betelgeuse.
Betelgeuse is a red supergiantAldebaran is an orange giant.
Polaris is the closest of the three stars.
Betelgeuse is a red giant therefore its surface is of red color with some white sun spots.
100,000,000,000,000,000,000,000,000,000,000,000 million years The truth:It is unlikely that a Saturn five could create enough velocity to get out of the solar system.If the payload had a Ion thruster in it and allowing that thruster could archive 1/4 light speed and the payload didn't have to...
Betelgeuse is a star and thus cannot support life - as we know it.
We can be quite certain that it has never done that.
Betelgeuse has a density of about 1.119 × 10−8 that of our Sun. See related question
Betelgeuse is 40,473,416.93376 AU' (Astronomical Units) from Earth.
3500 k (kelvin), 1 kelvin is -272.15°C
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...
Any date, less 640 years.
Sirius is a white main sequence star, whereas Betelgeuse is a red supergiant not on the main sequence.
Betelgeuse is only about 10 million years old - and is close to death already. It has already exhibited, an expansion and contraction of it's outer shell, which is a sure sign, that it will soon (astronomically) come to a final end as a supernova.
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.
Betelgeuse is the massive red giant star at the shoulder of the constellation Orion. The greater the initial mass of a star, the faster it develops, and the faster it ages. Betelgeuse is nearing the end of its "life", and will probably explode in a supernova relatively soon. However, "relatively...
Antares has a radius of about 800 solar radii whereas Betelgeuse has a radius of about 1,180 solar radii. Both are massive compared to our Sun. See related link for a pictorial comparison.
