Why does the sun have a luminosity of 1?
It really depends on the units used. Sometimes the Sun is used as a comparison for the brightness of other stars, or even galaxies - in this case, the Sun's luminosity is arbitrarily defined as 1, and a star that is 10 times brighter will have luminosity 10, for example. However, if you use other units, for example watts, you get quite different numbers (3.846×1026 watts for the Sun, according to the Wikipedia).
What is the luminosity of the sun?
The luminosity of the Sun is approximately 3.8 x 10^26 watts, which means it is emitting this amount of energy every second. This energy output is generated through nuclear fusion reactions in the Sun's core.
What is the luminosity of Betelgeuse?
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.
According to the Hertzsprung Russell Diagram what is the luminosity of the Sun?
The Sun is the main basis for many stellar parameters. A far as luminosity goes - it is 1.
What is the brightness of the sun?
The Sun has a brightness or apparent magnitude [See related question] of -26.74 (yes negative).
Is the sun measured by watts?
It's luminosity is: 3.846×1026 Watts
What is the suns luminosty?
The Sun's luminosity is 3.846 × 10 ^26 Watts.
What are the standard units of luminosity?
The answer is : watts

How is star luminosity measured?
A star's luminosity is measured according to the relevance to the sun. Basically for example, if a star is 8,300 degrees Celsius and has a luminosity of 0.001; the luminosity is compared to the sun.
What is the brightness of the sun?
The Sun has a brightness or apparent magnitude [See related question] of -26.74 (yes negative).
What is the luminosity class of the sun?
V
What is the luminosity of Deneb?
Deneb has a luminosity (apparent magnitude) of 1.25. However, in bolometric luminosity (solar units) Deneb is 54,000, whereas our Sun is 1.
What is a Polaris star luminosity?
The main star in the Polaris system has a luminosity which is 2500 times that of the Sun.
