Apparent magnitude Definition & Meaning - Merriam-Webster

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.

WebStars with apparent magnitude greater than about 6 are not visible to the naked eye. The magnitude scale is not linear in that a star that is double the magnitude of another does not appear to be twice as dim. Rather, the relation goes as follows: If one star has an apparent magnitude of m1 and another has an apparent magnitude of m2, then the ...
