Betelgeuse is part of the Orion constellation. It is the eighth brightest star in our sky.
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: 0.42 So Betelgeuse is brighter as viewed from Earth.
Both Antares and Betelguese are "red giant" stars..
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 isstill one of the brightest stars in our sky, because of its hugesize and luminosity.
No I don't think it will because there isn't enough stuff to make one
Betelgeuse is the reddish star on the top of the constellation.
That depends on the speed of the spaceship. If it were traveling at the speed of light, which is the maximum speed that any object can reach, it would take 640 years to get there.
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.
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. The biggest star ever discovered is the VY Canis Majoris, a red hypergiant with a radius of easily 2000 times bigger than that of the Sun. That is more than twice the radius of Betelgeuse. Also, the mass of VY Canis Majoris is around twice that of Betelgeuse.
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...
It's difficult to know exactly what Betelgeuse will become, but it will most likely explode as a supernova. The result will probably be a black hole, but depending on the magnitude of the explosion, it could become a neutron star or pulsar.
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 gravitationalcollapse of a "stellar nebula". Betelgeuse is an old star now, a red "supergiant". It would havebeen very different originally, of course.
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...
Betelgeuse marks the "Hunter's" right shoulder. For a northern-Hemisphere observer viewing the constellation, it's the bright, reddish star in the upper-left corner of Orion's main rectangle.
The same as all stars, hydrogen.
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.
The red colour means that it's surface temperature is cool < 3,700K. At that temperature, the spectrum of light is red.
No, Betelgeuse is a star. It is part of the constellation Orion.
I've heard it pronounced two ways: 1. Beetle-jooz (as in the movie character) 2. BATL-geez (with a long flat a, as in "wade") It is pronounced ba tle guese
Most definitely. Jupiter is a planet and Betelgeuse is a star. Oursun is much larger than Jupiter and Betelgeuse is much larger thanour 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.
Definetly but what kind,
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 Sun . Rigel has a radius of about 78 times that of our Sun . Betelgeuse has a mass of 18 times that of our Sun . Rigel has a mass of 17...
The circumference of Betelgeuse is about 1180 times the circumference of our sun.
No. Betelgeuse is a star well outside of the solar system.
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
Yes, a very large, VERY bright one. The only reason it looks tiny is because it is 640 light-years away.
Because our Sun is a lot closer. 93 million miles instead of 3.7 quadrillion. (3,762,239,880,000,000 miles)
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...
red giant, plantary nebula, white dwarf,black whole, red supergiant , supernova, neutron star
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.
Stars don't have crust, they are made of gas and plasma.
First of all, Betelgeuse is 640 light-years away from Earth. So,even if a rover is sent to this star at the speed of light, itwould take 640 years for it to get there. Second of all, once itreaches there, we would have to control the rover with radiosignals. The signals would have to be extremely...
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.
Just like every other star. There was a large collection of gases a long time ago. This mass started to accumulate over time, ultimately creating a hot,dense body of gas. The temperature is so high that nuclear fusion can be initiated and sustained.
No, Betelgeuse is a red star.
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.
The movie ghost beetlejuice will jump out. boo.........
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.
Betelgeuse is 640 light-years away from the Earth. 1 light-year is the distance traveled by light in 1 year. speed of light = 3 x 10 8 meters per second So, 1 ly = 3 x 10 8 x 365 x 24 x 60 x 60 = 9.46 x 10 15 meters 640 light-years = 640 x 9.46 x 10 15 = 6.05 x 10 18 meters 1...
It is the brightest type of star, Red Supergiant.
No, Betelgeuse is about 640 light-years from earth, but some stars are many billions of light-years away.
RA 5h 55min, DEC 7 deg 24 in The distance ("a") from Earth to Betelgeuse is about 427 lightyears and the distance ("b") from Earth to Rigel is about 772 lightyears. The angle between the two stars from Earth is 18.56 degrees. Knowing these three numbers, we can now use the "law of cosines"...
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...
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.
the universe apparently never stops going. Plus the galaxy's are included with the universe :)
yes! its brighter than our sun
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.
The radius of the star Betelgeuse is around 1,000 times larger thanthat of the Sun, and has a mass of roughly 20 times that of theSun. So, indeed it is a very large star.
Rigel is a lot hotter than Betelgeuse. . Rigel - 11,000K . Betelgeuse 3,500K
Proxima Centauri has an insignificant luminosity to Betelgeuse. Although it is the closest known star(4.2 light-years) to our Sun, it is virtually impossible to see because it is so dim. Betelgeuse, on the other hand, is a lot farther (640 light-years). Yet, it is one of the brightest stars in our...
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!
It's around 20 times heavier than our Sun.
Red supergiant
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.
It is part of the Orion constellation.
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.
Betelgeuse has less than a million years left, which is a very short time for a star.
The 9 th brightest star of the night sky, the Betelgeuse is a red super giant. If it were placed in our solar system, it would have reached the asteroid belt, engulfing Mercury, Venus, Earth and mars.
