As I taught about stars this semester an auditory manner in which to describe absolute and apparent magnitude occurred to me. In this activity volume (of music) will represent the brightness of stars. Absolute and apparent magnitude of the Sun (an aveage star) and Sirius ( a very bright star) will be compared.
- Star - a large celestial body that is composed of gas and that emits light
- Luminosity - the actual brightness of an object, such as a star
- Absolute magnitude - a measure of how bright a star would be if it were seen from a standard distance
- Apparent magnitude - the brightness of a star, as seen from Earth
