WebAbsolute magnitude is defined as the apparent magnitude that a star or object would have if it were observed from a distance of 10 parsecs (33 light-years; 3.1 × 10 14 kilometres; 1.9 × 10 14 miles). Therefore, it is of greater use in stellar astrophysics since it refers to a property of a star regardless of how close it is to Earth.
WebIn this class, we will describe how bright a star or galaxy really is by its luminosity. The luminosity is how much energy is coming from the per second. units are watts (W). Astronomers often use another measure, absolute magnitude. I think it is confusing.
