The apparent magnitude of an object is a measure of it's brightness as seen from Earth.
As we are located within the Milky Way, this value is impossible to obtain.
The Milky Way has a estimated absolute magnitude of -20.9
An estimation of the absolute magnitude is −20.9. See related question.
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
it has an apparent magnitude of 2.1
The apparent magnitude of Neptune is 7.8
Vega has an apparent magnitude of 0.03.
Apparent magnitude is the brightness of an object as seen from Earth without any atmosphere.
The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.
No - many orders of magnitude SMALLER
The apparent magnitude of the Cartwheel Galaxy is 15.2
The apparent magnitude of a star is a measure of its brightness.
The apparent magnitude is 2.4
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.
