WebMar 21, 2024 · Fortunately, there's a formula known as the Distance Moduluswhich is defined to calculate precisely this information. The equation is given by $$m-M=5\log_{10}(d_{pc}) - 5$$ where $m$ is the apparent magnitudeof your star, $M$ is the absolute magnitude, and $d$ is the distance from the star, in units of $\mathrm{parsecs}$. WebThe scale below is intended to be roughly visual; the human eye's (dark-adapted) detection efficiency peaks around 495 nanometers, while the formal photoelectric V peak (a filtered band intended to be close to visual) is around 550 nm; CCDs tend to peak around 700 nm.

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.
