A glance at the night sky above Earth shows that some stars are much brighter than others ... Astronomers define star brightness in terms of apparent magnitude - how bright the star appears from Earth - and absolute magnitude - how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.
