Question

How does the pulsation of stars relate to their distance from earth?

Answer 1

Hey Mate..

To do so, astronomers calculate the brightness of stars as they would appear if it were 32.6 light-years, or 10 parsecs from Earth. Another measure of brightness is luminosity, which is the power of a star — the amount of energy (light) that a star emits from its surface.
