When Referring To Stars What Is The Difference Between Apparent Brightness And Luminosity. The luminosity of a star, on the other hand, is the amount of light it emits from its surface. Apparent brightness is the amount of energy that the star emits per second that reaches a given area here on earth. Understand how astronomers specify brightness with magnitudes; We have seen how a star’s brightness is noted to give its apparent magnitude and if we know its distance we can also calculate its absolute magnitude. When astronomers speak of the luminosity of a star, they’re speaking of a star’s intrinsic brightness, how bright it really is. When i say apparent brightness, i mean how bright the star appears to a detector here on earth. Luminosity is the total amount of energy. Thus, the determination of apparent. Astronomers are careful to distinguish between the luminosity of the star (the total energy output) and the amount of energy that happens to reach our. From this we can get meaningful. Explain the difference between luminosity and apparent brightness; The apparent brightness of a star depends on both its luminosity and its distance from earth. Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from earth — and absolute magnitude — how bright the star appears at a standard distance of.
