How Does Absolute Magnitude Vary with Object Type?

Different types of astronomical objects have distinct ranges of absolute magnitudes:

Stars: The absolute magnitude of stars can range from around -10 for the most luminous supergiants to +15 for the faintest red dwarfs.
Galaxies: Galaxies typically have absolute magnitudes that range from around -25 for the brightest elliptical galaxies to -15 for the faintest dwarf galaxies.
Planets: The absolute magnitudes of planets are generally much higher (fainter) since they do not produce their own light but reflect the light of their parent star. For example, Earth's absolute magnitude is about +4.83.
