How much is luminosity per year
WebSo I know that the Sun's luminosity is $3.839 \cdot 10^{26}$. What I want is the luminosity per square meter at the Earth's surface. So this is what I have got so far: I know the distance to the Earth from the Sun is $149.60 \cdot 10^9$ m. WebHere, we examine that claim. Let us assume that the Sun is shrinking is by gravity. Then from the equation that scientists have for the change of the Sun's luminosity (luminosity is an …
