An object's surface brightness depends on its surface luminosity density, i.e., its luminosity emitted per unit surface area. In visible and infrared astronomy, surface brightness is often quoted on a magnitude scale, in magnitudes per square arcsecond in a particular filter band or photometric system. Measurement of the surface brightnesses of celestial objects is called surface photometry. The total magnitude is a measure of the brightness
