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
The apparent magnitude of Neptune is 7.8
Vega has an apparent magnitude of 0.03.
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 is 2.4
The apparent magnitude of a star is a measure of its brightness.
One way to describe a star's brightness is by its apparent magnitude, which is how bright it appears from Earth. Another way is by its absolute magnitude, which measures how bright a star would appear if it were placed at a standard distance of 10 parsecs from Earth.
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.
Apparent magnitude is the measure of how bright a star appears as seen from Earth. This scale is based on a star's brightness perceived by human observers. The lower the apparent magnitude, the brighter the star appears.
