What makes apparent magnitude different from absolute brightness? Give an example in your response.

~~~There wasn't just 'science' for a subject so i just put biology

Apparent magnitude

the magnitude of a star as it appears to an observer on the earth. and absolute brightness is the apparent brightness a star would have if it were placed at a standard distance of 10 parsecs from Earth

ex of apparent magnitude.

The comet of 1652, so carefully observed by Hevelius, almost equaled themoon in apparent magnitude.

sorry i dont have an example of absolute brightness
