Which star is brighter Aldebaran or Betelgeuse?
Betelgeuse is brighter.
This could be considered a trick question. Generally, Betelgeuse is brighter BUT Betelgeuse is what we call a variable star and there are times when it is fainter than Aldebaran.
Betelgeuse is more luminous than Aldebaran.
becuase it just is
Rigel is brighter than Betelgeuse.
Betelgeuse is a red supergiant Aldebaran is an orange giant.
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.
Betelgeuse is regarded as the 9th brightest star as we see it, and Antares is 16th.
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.
Absolutely, there is Sirius, Pollux, Arcturus, Rigel, Aldebaran, Betelgeuse, and Antares.
Yes, Betelgeuse is one of the brighter stars in the sky. The red star of Orion's left shoulder is Betelgeuse.
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.
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.

Betelgeuse and Aldebaran are red stars.
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
No, there are lots of red giant stars, too many to count. Betelgeuse and Aldebaran just happen to be close to us and bright in the sky, so we see them easily.
Rigel is brighter.
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
No. The sun has an absolute magnitude of 4.83. By comparison, Betelgeuse has an absolute magnitude of -5.85. Lower numbers indicate a brighter star. In this case Betelgeuse is actually several thousand times brighter than the sun. The sun is the brightest star as measure by apparent magnitude, which is how bright a star looks from a given location and depends on both absolute magnitude and distance.
A typical red giant is Betelgeuse which has an absolute magnitude of -4.5. That makes it 9 magnitudes brighter than the Sun so it is 4000 times brighter.
yes! its brighter than our sun
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.
Aldebaran is the brightest star in the constellation of the Gemini
Aldebaran star diameter is 59,770,000 kilometers (miles unknown)
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.
Each constellation is made of stars that are all approximately in the same direction as seen from Earth. That does not mean they are grouped together in 3D space. The bright star in Taurus is Aldebaran, which is 60-70 light years away and about 100 times brighter than the Sun. The Pleiades is an open cluster that is in Taurus, about 500 light-years away, and the brightest star in the Pleiades, Alcyone, is 2-3 times… Read More
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
It all depends on where you view them from. The apparent magnitude, is defined as being viewed from Earth Betelgeuse: 0.58 - Brighter Zeta Orionis (Alnitak) = 1.70 The absolute magnitude, is defined as being viewed from a distance of 10 parsecs. Betelgeuse: -5.14 Zeta Orionis: -5.25 - Brighter

Yes, there is a star named Betelgeuse. Betelgeuse is a red star located on the constellation of Orion.
Why is Rigel appears brighter than aldeberan even though aldeberan is technically brighter than Rigel?
The absolute magnitude of Rigel is -7.92 while that of Aldebaran is -6.41. This means that Rigel is approx 4 times brighter than Aldebaran - technically. So the question is based on a flawed grasp of absolute magnitude.
The star Betelgeuse is a supergiant.
No, Betelgeuse is a red star.
Betelgeuse is a supergiant star.
No. Betelgeuse is a single star.
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
Our Sun is a medium-sized star with an absolute magnitude of 4.83. The red giant star Betelgeuse (at the shoulder of the constellation Orion) has an absolute magnitude of -6.05. Lower numbers mean brighter stars, with negative numbers being brighter than positive numbers. So Betelgeuse is THOUSANDS\\\\\MILLIONS of times brighter than the Sun - or at least, they would be if you were halfway in between them. But because Betelgeuse is about 650 light-YEARS away… Read More
No, it is much too far away for that. We will see it get much brighter in the sky, much brighter than any other star. But, other than the pretty light show, it won't affect us.
Probably not much; it would depend on which star, and the orientation of the axis of rotation of the star is. There are no stars particularly new the Sun that could go supernova. Probably the most likely "near" star to supernova is Betelgeuse, the red supergiant at the shoulder of the constellation Orion. Betelgeuse is abut 640 light years away, which is an ideal distance for a supernova. When (not if!) Betelgeuse explodes, it will… Read More
Aldebaran is a red giant with a spectral class of K5.
Aldebaran is an orange giant star in the zodiac constellation of Taurus.
No, Betelgeuse is a super giant star.
The Sun is 8 light MINUTES away, while Betelgeuse is 600 light-YEARS away. Even though Betelgeuse is hundreds of times more massive, and millions of times brighter, it is much further AWAY.
Which star has a higher luminosity and a lower surface temperature than the sun Rigel Bernard's star Alpha Centauri or Aldebaran?
Aldebaran, which is a red giant star.
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
No, Betelgeuse is a star.
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 , C or D? For A, bright giant, 46 solar radii. So a simple question can be so difficult. All are giants except Alpha Centauri, however… Read More
Betelgeuse will die in a massive explosion called a supernova. When this happens it will appear brighter than the full moon.
