Luminosity is related to temperature and distance.
A cool and thus less luminous star would be brighter than a more luminous star at a greater distance.
Our Sun is a relatively cool star in comparison to say Rigel, but because it is closer it appears more luminous and brighter.
What else can I help you with?
How much more luminous than the sun is the star Rigel?
Rigel is approximately 120,000 times more luminous than the Sun. It is a blue supergiant star, which is much larger and hotter than our Sun, resulting in its high luminosity.
Is the star Rigel luminous?
Very!! It is about 66,000 times more luminous than our Sun
What type of star is cursa?
Cursa is a binary star system consisting of a B-type star and a fainter star. The B-type star is a hot, blue-white star that is more massive and luminous than the Sun.
Who is the Brightest star other than sun?
Sirius is the brightest star in the night sky.
Why one star may appear brighter than other star?
One star may appear brighter than another star due to several factors, including its size, temperature, distance from Earth, and luminosity. A larger, hotter, closer, or more luminous star will typically appear brighter in the night sky compared to a smaller, cooler, more distant, or less luminous star.
Explain how a red star can be more luminous than a bluish-white star?
A red star can be more luminous than a bluish-white star if it is larger in size and/or hotter in temperature. The luminosity of a star is determined by its size and temperature, with larger and hotter stars emitting more energy. Therefore, a red star that is larger and hotter than a bluish-white star can be more luminous.
Which star is more luminous R136a1 or VY Canis Majoris?
R136a1 is the most luminous at about 8,700,000 times more than the Sun. VY Canis Majoris is only 450,000 times more luminous than our Sun.
How much more luminous than the sun is the star Rigel?
Rigel is approximately 120,000 times more luminous than the Sun. It is a blue supergiant star, which is much larger and hotter than our Sun, resulting in its high luminosity.

How can Arcturus be cooler and more luminous than the Sun?
Arcturus is cooler and more luminous than the Sun because it is a giant star, which means it has exhausted the hydrogen fuel in its core and expanded, causing its surface temperature to be lower than the Sun's but its overall size and brightness to be greater. This combination of lower temperature and larger size results in Arcturus being cooler and more luminous than the Sun.
Why does Rigel shine as bright as Betelgeuse even though Rigel is much smaller than Betelgeuse?
Rigel appears as bright as Betelgeuse because it is hotter and more luminous, even though it is smaller. The luminosity of a star depends on both its temperature and size, so a hotter, more luminous star can shine as brightly as a larger, cooler star.
What are larger and more luminous than red giants?
Supergiants are bigger and more luminous than the red giants. Supergiants are stars that have a mass that is eight times more than the sun.
Is Rigel brighter than the Sun?
no you are stupid if you are answering this
Is rigel a dwarf star?
No Rigel is a huge, blue supergiant of spectral class B8 Ia, Rigel has an intrinsic brightness about 40,000 times as luminous as that of the sun.
