WebThe supergiant Betelgeuse is the brightest, with an absolute magnitude of -5.6. The sun is intrinsically the dimmest! How can we calculate the absolute magnitude of a star? There are two general ways. One method is to determine the distance to the star, measure the apparent magnitude, and scale the apparent magnitude to a distance of 10 pc. Apparent magnitude (m) is a measure of the brightness of a star or other astronomical object observed from Earth. An object's apparent magnitude depends on its intrinsic luminosity, its distance from Earth, and any extinction of the object's light caused by interstellar dust along the line of sight to the … See more The scale used to indicate magnitude originates in the Hellenistic practice of dividing stars visible to the naked eye into six magnitudes. The brightest stars in the night sky were said to be of first magnitude (m = 1), whereas the … See more The dimmer an object appears, the higher the numerical value given to its magnitude, with a difference of 5 magnitudes corresponding to a brightness factor of exactly 100. … See more • Distance modulus • List of nearest bright stars • List of nearest stars • Luminosity in astronomy • Surface brightness See more Precision measurement of magnitude (photometry) requires calibration of the photographic or (usually) electronic detection apparatus. … See more The magnitude scale is a reverse logarithmic scale.

WebAccording to Wikipedia, the apparent magnitude can be given as: m x = − 2.5 log 10 ( F x / F x 0) where F x is the observed flux and F x 0 is a reference flux (in other words, this equation provides the difference of apparent magnitude between two observed values). WebSixth magnitude stars were assigned to stars that were barely visible to the unaided eye under good conditions. It was then theoretically determined that the ratio of first magnitude to sixth magnitude was 100 to 1. Then a logarithmic scale of 2.512 between magnitude levels is to be implemented.
