Astronomers do not actually measure the light energy, or luminosity, produced by each star, but instead define each star’s energy in relation to the sun, which has a luminosity of 400 trillion trillion watts. For example, Alpha Centauri has a luminosity 1.3 times that of the sun, while Rigel, a star that is 325 times further away from the earth than is Alpha Centauri, has a luminosity 150,000 times that of the sun.
