measure of brightness for celestial objects, as seen from Earth
Apparent magnitude is a number that measures how bright a star or other object in the sky appears to us when we look at it from Earth. It matters because it helps astronomers and stargazers compare the brightness of different celestial objects and understand what we can see in the night sky.

Apparent magnitude (m) is a measure of the brightness of a star, astronomical object or other celestial objects like artificial satellites. Its value depends on its intrinsic luminosity, its distance, and any extinction of the object's light caused by interstellar dust or atmosphere along the line of sight to the observer.
