What is the luminosity of polaris?
Polaris has an absolute visual magnitude of about -3.2, making it over 4,000 times more luminous than the Sun. Its luminosity is approximately 1,200 times that of the Sun in terms of total energy output.
What is Porrima's absolute magnitude?
The absolute magnitude of Porrima is 3.04.
Explain why size is the only factor that determines the stars absolute magnitude?
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
What is the magnitude of Alpha Arietis?
the absolute magnitude is 0.48 <(-.-<)
The light from Sirius is 24.2 times more intense than light from Polaris What is the magnitude difference?
Apparent magnitude of Sirius = -1.44Apparent magnitude of Polaris = 1.97To the Earthbound observer, Sirius appears (1.44 + 1.97) = 3.41 magnitudesbrighter than Polaris.1 magnitude = (100)1/6 times as bright3.41 magnitudes = (100)3.41/6 = 13.7 times as bright as Polaris
What is the absolute brightness of Polaris?
The absolute magnitude of the main star in the Polaris system is -3.6
How many times is the star polaris brighter than the sun?
Polaris, also known as the North Star, is approximately 2,500 times brighter than the Sun. This brightness is measured in terms of absolute magnitude, where Polaris has an absolute magnitude of about -3.6, compared to the Sun's absolute magnitude of about +4.8. However, the apparent brightness of stars can vary based on their distance from Earth.

How many times more luminous is Polaris than Procyon A?
To determine how many times more luminous Polaris is compared to Procyon A, we need to calculate the difference in their luminosities. Polaris has an absolute visual magnitude of -3.64, while Procyon A has an absolute visual magnitude of 2.66. Using the formula 2.5^((M2-M1)/-1), where M1 and M2 are the absolute magnitudes of Polaris and Procyon A respectively, we find that Polaris is approximately 3,372 times more luminous than Procyon A.
