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. Explanation The scale...
When the magnitude scale was fixed, Vega happened to be close to zero magnitude. Therefore the visual magnitude of Vega was decided to be, by definition, zero at all wavelengths.
It is or has been known by a number of other names, including Arided, Aridif, HR 7924, and HD 197345. At an apparent magnitude of 1.25, it is the twentieth brightest star as seen from Earth in the ...
