Luminosity of the Sun
Answers to Common Questions
White Dwarfs are degenerate stars. They are created when the host star has exhausted it's supply of hydrogen. Its luminosity comes from the emission of stored thermal energy, it has no other means of energy as all fusion has ceased nor can ...
the luminosity of the sun mesured in watts is a big number so heres something a little simpler 3.839 × 10 26 W
It's easy. Measure its (apparent) brightness, measure it's distance, and use the inverse square law. The sun emits some amount of total energy from its surface every second (this is the luminosity of the sun). As that energy is radiated awa...

If you think a bit, then you realize that that can only be done indirectly. The climate on Earth (during the Jurassic and other periods) is due to the luminosity of the Sun, but convoluted by other effects, such as distribution of landmas...

I would say no. As I've noted before, the geological record indicates that climates have grown warmer and colder on Earth in cycles that correlate only very roughly to long-scale changes in solar luminosity (there have been repeated ice a...

No, because the sun produces light. To be luminous, the sun would have to reflect light.

A solar luminosity is equal to the current luminosity of the Sun, which is 3.839 × 10 26 W, or 3.839 × 10 33 erg/s. So dividing one solar luminosity with the Suns luminosity gives 1. Also it is a lot easier talking about a luminosity of 1 r...

Compared with the Sun it is massive, about 45 times as large so the energy it is putting out dwarfs anything the Sun is presently putting out.

Assuming main sequence stars - the temperature would be about 15,000 Kelvin.
