Betelgeuse, a red supergiant star located in the constellation Orion, has an apparent magnitude of approximately 0.42. This makes it one of the brightest stars in the night sky. Its brightness can vary due to its pulsating nature, but it generally remains within this range, making it easily observable to the naked eye.

What is the magnitude Betelgeuse?
Betelgeuse has an apparent magnitude of 0.58 and on absolute magnitude of -6.05.
Is the Betelgeuse star brighter than the Antares star?
Betelgeuse and Antares are both prominent red supergiant stars, but Betelgeuse is generally brighter than Antares. Betelgeuse has an apparent magnitude of about 0.42, while Antares has an apparent magnitude of around 1.0. This means that Betelgeuse appears brighter in the night sky compared to Antares. However, both stars are among the brightest in their respective constellations.
What star is brighter Betelgeuse or Rigel?
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.
How many times brighter is Aldebaran the star than Betelgeuse?
Aldebaran is approximately 2.5 times brighter than Betelgeuse when comparing their apparent magnitudes. Aldebaran has an apparent magnitude of about +0.85, while Betelgeuse has an apparent magnitude of around +0.58. This means that Aldebaran appears less luminous in the night sky compared to Betelgeuse, despite being a significant star in its own right. However, in terms of intrinsic brightness, Betelgeuse is actually much more luminous than Aldebaran, being a red supergiant star.
Why is Betelgeuse brighter than Antares?
Betelgeuse is brighter than Antares primarily due to its size and proximity. As a red supergiant star, Betelgeuse has a larger radius and emits more light than Antares, which is a red supergiant as well but is farther away from Earth. Additionally, Betelgeuse's apparent magnitude is about 0.42, while Antares has an apparent magnitude of about 1.06, making Betelgeuse appear brighter in our night sky. The combination of Betelgeuse's intrinsic luminosity and its relative closeness contributes to its brighter appearance.

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 .

What star is brighter Betelgeuse or Aldebaran?
Betelgeuse is generally brighter than Aldebaran. Betelgeuse, a red supergiant in the constellation Orion, has an apparent magnitude of about 0.42, while Aldebaran, a red giant in the constellation Taurus, has an apparent magnitude of around 0.87. This makes Betelgeuse one of the brightest stars in the night sky, easily outshining Aldebaran. However, both stars are prominent and notable in their respective constellations.
Is Vega or Betelgeuse the brightest star?
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.
Which star is brighter Vega or Betelgeuse?
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.
What is the brightness of Betelgeuse?
