Answer:
Absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer
Step-by-step explanation:
The light we see on the Earth coming from the starts isn’t the real light it reflects.
Absolute brightness or magnitude is the term that describes the luminosity and the light which we would observe if we stood in front of the star; it’s the real brightness of the star.
Apparent lightness or the magnitude is the luminosity of the star that can be observed from the earth. It depends on the absolute brightness, on the distance, and on anything that is between the observer and the star, such as interstellar dust.
