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.

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 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 are Barnard's star and Antares alike?
Barnard's Star and Antares are both red dwarf stars. However, Antares is a red supergiant star that is much larger and brighter than Barnard's Star. Both are part of the Milky Way galaxy and can be seen from Earth with the naked eye.
Why is Jupiter in the night sky brighter than betelgeuse?
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.
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.
