WebThe total energy output per second of a star is called its luminosity, L, sometimes written as L*. Our Sun's luminosity is about 3.84 × 10 26 W. Rather than use absolute values it is often convenient to compare the luminosity of a star, L* to that of the Sun so that for instance it may be 1,000× LSun. The source of energy in stars is ...

How To Measure Distances Of Stars By Parallax Method?

WebHow do we measure the distances to things in space? Answer: It is not an easy thing to measure the distances to objects in the universe since these objects are usually very far away. We can't just run out there with a ruler! To measure distances in the universe, we will need to construct what is commonly referred to as a "cosmic distance ladder".
