A scale for measuring the actual brightness of a celestial object without accounting for the distance of the object. Absolute magnitude measures how bright an object would appear if it were exactly 10 [..]

(n) - the luminosity of stars as if thery were seen from the same

The brightness a star would have if it were placed 10 pc (32.6 ly) from the Earth.

A classification scheme, which compensates for the distance, differences to stars. It calculates the brightness that stars would appear to have if they were all at a defined, standard distance of 10 p [..]

The magnitude a star would appear to have if at a distance of 10 parsecs from Earth. Absolute magnitude is a measure of a star’s intrinsic luminosity and allows us to directly compare stars.

The magnitude that would be assigned to a star if it were placed at a distance of 10 parsecs from the observer. Stars closer to us than that distance would appear fainter. Stars farther from the solar [..]

(n.) The magnitude that a star would appear to have if it were at a distance of ten parsecs from us.

the brightness that a star would have at a distance of 32.6 light-years from Earth
