The absolute magnitude of a star is the amount of light received by earth?
Earth's apparent magnitude would depend on where it is viewed from. For instance, from Saturn, the apparent magnitude is 1.45. From Mars is would be somewhat higher.
Apparent Magnitude It is a scale where each successive integer is half as bright as the one below it (-3 is twice as bright as -2, etc). For example, Venus is around mag -4, and the human eye can see object up to mag 7

1.Luminosity is the amount of light emitted from a certain light source whereas brightness is the amount of light manifested or received. 2.The area of illumination is inversely proportional to brightness whereas luminosity isn't. 3.Brightness is usually expressed in 'Lumens' whereas luminosity is expressed in candela per square meter (photometry).
The amount of starlight received on Earth is called apparent magnitude. This is the measurement of how bright the stars appear from Earth.
