Big bang - Study guides, Class notes & Summaries

Absolute brightness the intrinsic brightness of a star that depends only on its luminosity. Apparent brightness how bright a star appears to an observer on Earth. Mpc Astronomers describe the apparent brightness of a star as the ratio between the brightness of the star to the brightness of the Sun when viewed from a distance of 1 _____________ . For example, a star with an apparent brightness of 10 is 10 times brighter than the sun would be if viewed from a distance of 1 _______...
