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.
Betelgeuse is luminous because it is a red supergiant star in the late stages of its evolution. Its large size and high brightness are due to its immense amount of energy being produced as it fuses heavy elements in its core, leading to its intense brightness compared to smaller, main-sequence stars.
Betelgeuse has a luminosity that is around 100,000 times that of the Sun. It is classified as a red supergiant star and is one of the brightest stars visible to the naked eye. Despite its high luminosity, Betelgeuse is also known for its variability in brightness.
Betelgeuse is a red supergiant star located in the constellation of Orion. It is one of the largest and brightest stars visible to the naked eye from Earth. Betelgeuse is known for its variable brightness and is expected to eventually explode in a supernova.
Betelgeuse is a semi-regular variable star, meaning it does not have a consistent period like a regular variable star. Its brightness fluctuates irregularly over periods of months to years.
Betelgeuse is a red supergiant star located in the Orion constellation. Its light exhibits a small Doppler shift due to its motion relative to Earth, but this shift is not significant compared to its overall distance and size. The Doppler shift of Betelgeuse's light is mainly influenced by its own pulsations and variations in brightness.
Betelgeuse is a red supergiant star located in the constellation of Orion. It is known for its irregular shape and variability in brightness, which is attributed to its pulsations and changes in its surface temperature and size. Betelgeuse also exhibits large convective cells on its surface that contribute to its complex and dynamic appearance.
