  • Star Brightness: Distance vs. Absolute Magnitude Explained
    The star that is closer to Earth would appear brighter in the night sky.

    Here's why:

    * Absolute magnitude measures a star's intrinsic brightness, meaning how much light it actually emits. Two stars with the same absolute magnitude are equally luminous.

    * Apparent magnitude is what we see from Earth. It's affected by both a star's absolute magnitude and its distance from us.

    * Light spreads out as it travels. The farther away a star is, the more its light spreads out, making it appear dimmer.

    Therefore, even though both stars have the same absolute magnitude, the closer star will have a brighter apparent magnitude, making it appear brighter in the night sky.
