magnitudes of two objects corresponds to a ratio of 100 in their luminosities, and a difference of n magnitudes in absolute magnitude corresponds to a luminosity ratio of 100^n/5. For example, a star of absolute magnitude M_V = 3.0 would be 100 times as luminous as a star of absolute magnitude M_V = 8.0 as measured in the V filter band. The Sun has absolute magnitude M_V = +4.83. Highly luminous objects can have negative absolute magnitudes: for example, the Milky Way
