Which star is larger rigel or betelgeuse?
Betelgeuse because it is a Red Supergiant.
Betelgeuse is much larger than Rigel.
Rigel is brighter than Betelgeuse.
Rigel is a lot hotter than Betelgeuse. Rigel - 11,000K Betelgeuse 3,500K
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, Rigel is hotter. Rigel is a blue star with a temperature of about 11,000 K, and Betelgeuse is a red star with a temperature of about 3,500 K.
Even though Betelgeuse is much larger, Rigel is brighter due to its much higher temperature. Rigel is about 11,000 K and Betelgeuse is only about 3,500 K.
Betelgeuse is a red supergiant star and the Rigel is a blue supergiant. Both are in the same constellation Orion
Betelgeuse is around 10 times greater in diameter than Rigel.
By it's spectrum. If it appears blue or white then it is hotter than a red or orange star. Rigel is a blue-white star whereas Betelgeuse is a red star.
Very many of them are much larger than the Sun, for example Aldeberan, Betelgeuse, Antares, Deneb, Rigel, etc.
Betelgeuse has an apparent magnitude of 0.42(v) and an absolute magnitude of -6.02. Rigel has an apparent magnitude of 0.12 and an absolute magnitude of -7.04. So Rigel is brighter.
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 times that of our Sun
Rigel is blue and Betelgeuse is red.
It is Betelgeuse, though Rigel is the brightest star in the constellation.
Rigel is the brightest star in Orion, Betelgeuse is the 2nd brightest
It shines as brightly because of the distance it has from earth and it has to do with how old the star is.
Rigel is brighter.
Simply because Rigel is hotter.
the examples of stars are Rigel,sun,Sirius,Betelgeuse,Capella,Vega,
Generally, true, but there are rare exceptions. For example, Betelgeuse is "Alpha Orionis" while Rigel, generally brighter then Betelgeuse, is "Beta Orionis". Betelgeuse is a somewhat variable star, and when the Bayer designations were assigned, Betelgeuse was the brighter star.
No, it is blue (very hot). Betelgeuse, also in the constellation of Orion, is red.
Betelgeuse or Alpha Orionis and Rigel or Beta Orionis are in the constellation of Orion the Hunter.
Orion is the most prominent constellation in the sky, so it has lots of prominent stars. Two in particular stand out. They are Rigel and Betelgeuse. Rigel is a very bright star in the bottom right corner, the brightest star in Orion. In the top left is Betelgeuse, also very bright but noticeably different in colour to Rigel, as it is a red giant star.
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.
Betelgeuse and Rigel are the two brightest stars in the constellation of Orion. They are very easy to spot, with Betelgeuse being at the top left and Rigel at the bottom right. Comparing the two it is also easy to notice the difference in colour as Betelgeuse is a red supergiant and looks reddish in colour, very different to Rigel.
Absolutely, there is Sirius, Pollux, Arcturus, Rigel, Aldebaran, Betelgeuse, and Antares.
Rigel is hotter by a long way with a temperature of 11,000 Kelvin, whereas Betelgeuse is a cool 3,500 Kelvin
Rigel is approximately ten times LARGER than Sirius
The radius of Rigel is 74 times larger than the radius of our sun. The volume of Rigel is therefore 402'224 times larger than the volume of our sun.
Usually, the beta star. Stars are given names based on the constellation that they are in, with the brightest star in the constellation being "Alpha", the second brightest being "Beta, and the third-brightest being "Gamma" - and so on through the rest of the Greek alphabet. However, stars _can_ change their brightness. In the constellation Orion, the red supergiant star Betelgeuse was, in the 1600's when the stars were cataloged, the brightest star in Orion… Read More
Here are the top 3, #3 Betelgeuse, #2 Rigel, #1 VY Canis Majors
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.
The red super giant Betelgeuse (left shoulder of Orion) or Rigel (the right knee, also in Orion).
Rigel and Betelgeuse don't orbit each other. They are hundreds of light-years away from each other.
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 and Rigel
Answer When Bayer prepared his catalogue, there was no way to measure stellar brightness precisely. Traditionally, the stars were assigned to one of six magnitude classes, and Bayer's catalog lists all the first-magnitude stars, followed by all the second-magnitude stars, and so on. However within each magnitude class, there was no attempt to arrange stars by relative brightness. For example, in the Orion constellation, Bayer first designated the two 1st-magnitude stars, Betelgeuse and Rigel, as… Read More
Orion is a constellation, a GROUP of stars, not a single star. There are many different kinds of stars in Orion including Betelgeuse, a red supergiant, and Rigel, a blue supergiant.
No. Betelgeuse is quite large, but there are many stars even larger. See the related question for more info.
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.
Yes. Rigel is the right leg of the constellation Orion and is the 6th or 7th brightest star in the sky. Rigel and all of Orion are best seen in Winter (Summer for the Southern Hemisphere) and are close to directly overhead at around 10:00 PM at Christmas. Rigel can easily be found by locating the Red Supergiant Betelgeuse (10th brightest star in the sky) and the three stars that make Orion's Belt. Rigel is… Read More
Sirius, polaris, cygnus, betelgeuse, & rigel
Betelgeuse is just one star. A galaxy can contain hundreds of millions of stars, so a galaxy is much bigger.
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.
Betelgeuse and Rigel are both in the top 10 brightest stars in the sky. They have been seen bright in the sky even since cavemen looked up. So, they were discovered about the same time.
It is common for astronomers to identify stars in a constellation with Greek alphabets. This is called the "Bayer designations". Bayer, a German astronomer, designated the stars in a constellation according to brightness, but this is not always the case. Here, Betelgeuse is not as bright as Rigel but it is called Alpha Orionis, rather than Beta Orionis. One reason for this is because 400 years ago, nobody could accurately determine which star was brighter… Read More
The star Rigel is a Blue supergiant.
Rigel, Betelgeuse. Comment: They are two of my favourite stars, but they aren't in the Solar System. There's only the Sun that's a star in our Solar System.
