Apparent Magnitude

Apparent magnitude is a measure of how bright a celestial object appears from Earth. It is a scale where lower numbers indicate brighter objects, with the brightest stars assigned negative values. This measurement considers the brightness as seen from our vantage point, including the effects of distance and any obscuring factors like dust or atmosphere. For example, the Sun has an extremely low (very bright) apparent magnitude, while distant stars have higher (fainter) values. Apparent magnitude helps astronomers compare how bright objects appear in the sky at a given time, though it doesn't necessarily reflect their true intrinsic brightness.
