Here's why:
* Brightness and Distance: The apparent brightness of a star (how bright it appears to us) depends on its intrinsic luminosity (how much light it actually emits) and its distance from Earth.
* Inverse Square Law: The brightness of light decreases with the square of the distance. This means that if a star is twice as far away, it will appear four times dimmer.
* Example: A star that is intrinsically very bright but incredibly far away might appear fainter than a smaller, less luminous star that is much closer to Earth.
