Q. What is Magnitude?
A. The degree of brightness of a celestial body designated on a numerical scale, on which the brightest star has magnitude −1.4 and the faintest visible star has magnitude 6, with the scale rule such that a decrease of one unit represents an increase in apparent brightness by a factor of 2.512. Also called magnitude.
The brighter an object appears, the lower the value of its magnitude, with the brightest objects reaching negative values.
The Sun has an apparent magnitude of −27, the full moon −13, the brightest planet Venus measures −5, and Sirius, the brightest visible star in the night sky, is at −1.5
