Final answer:
The attribute that might change depending on the distance to a star is its apparent magnitude, because it's influenced by the star's distance from Earth due to the inverse square law of light.
Step-by-step explanation:
The attribute that might change depending on the distance to a star is its apparent magnitude. Apparent magnitude refers to how bright a star appears from Earth and can vary based on the star's distance from our planet. The luminosity of a star, or the total energy it emits per second, does not change with distance; it is an intrinsic property of the star. Similarly, a star's composition and absolute magnitude, or intrinsic brightness if placed at a standard distance, remain constant regardless of how far it is from us. However, apparent magnitude is directly affected by distance due to the inverse square law of light, which states that the apparent brightness of an object decreases with the square of the distance from the observer.
