I apologize for the confusion. The brightness of a star as it appears to us on Earth depends on multiple factors, including its distance from Earth, its intrinsic luminosity or brightness, and any interference from dust or other objects in space. While the distance from Earth is a significant factor, the composition of the star and your position on Earth can also play a role. For example, if you are in a heavily light-polluted area, the brightness of the star may appear dimmer due to the surrounding light. Similarly, the composition of the star, such as its temperature and size, can affect its apparent brightness.
so which is it?
The primary factor that determines how bright a star appears to us on Earth is its distance from Earth. The farther away the star is, the dimmer it appears. However, other factors such as the intrinsic luminosity or brightness of the star, its composition, and any interference from dust or other objects in space can also influence its apparent brightness.
