The apparent magnitude (m) of a celestial body is a measure of its brightness as seen by an observer on Earth, normalized to the value it would have in the absence of the atmosphere.
The brighter the object appears, the lower the value of its magnitude.
The variation in brightness between two luminous objects can be calculated by subtracting the magnitude number of the brighter object from the magnitude number of the fainter object, then using the difference as an exponent for the base number 2.512; that is to say (mf − mb = x; and 2.512x = variation in brightness).
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
Vega has an apparent magnitude of 0.03.
The apparent magnitude of Neptune is 7.8
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.
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.
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.
it is an apparent magnitude of 1.74
