The 24 pages that link to Absolute magnitude, each with the reason it gives.

• Cosmic distance ladderRelated: It expresses intrinsic brightness in the standardized form used to calibrate candles.

• Apparent magnitudeCompared with: Unlike apparent magnitude, it removes distance as a source of brightness difference.

• Hertzsprung–Russell diagramRelated: Russell’s version used absolute magnitude to compare intrinsic stellar brightness.

• Interstellar extinctionRelated: Comparing intrinsic and observed brightness exposes the dimming caused by extinction.

• PhotometryRelated: It separates intrinsic luminosity from the object's distance.

• Stellar parallaxRelated: A parallax distance allows a star’s intrinsic brightness to be expressed as absolute magnitude.

• Standard candleRelated: It expresses intrinsic brightness on the same scale as apparent magnitude.

• Stellar luminosityRelated: It expresses intrinsic brightness through a standardized distance convention.

• Color–magnitude diagramRelated: It replaces observed brightness with intrinsic luminosity when distance is known.

• Henrietta Swan LeavittRelated: The period–luminosity relation predicts intrinsic brightness from a Cepheid’s period.

• SiriusRelated: It separates Sirius’s intrinsic output from the advantage of its proximity.

• Distance modulusRelated: It supplies the standardized intrinsic-brightness term compared with apparent magnitude.

• Tully–Fisher relationRelated: The relation predicts intrinsic brightness, commonly expressed as absolute magnitude.

• Galaxy luminosity functionRelated: Galaxy luminosity functions are often plotted in magnitudes rather than physical luminosity.

• Minor planetRelated: Astronomers use it to estimate minor-planet size when paired with a reflectivity estimate.

• Asteroid familyRelated: It helps estimate fragment sizes and compare a family's size distribution.

• Bolometric luminosityRelated: Its bolometric version expresses total output on a distance-standardized magnitude scale.

• Ejnar HertzsprungRelated: Comparing absolute magnitudes exposed stars that were unusually luminous for their spectral types.

• DenebRelated: It distinguishes Deneb’s enormous intrinsic output from its brightness as seen from Earth.

• Planetary nebula luminosity functionNarrower topic: The cutoff is calibrated as an intrinsic magnitude before its apparent value is used as a ruler.

• Superluminous supernovaRelated: It allows peak brightnesses to be compared across different distances.

• Geometric albedoRelated: Together with size, absolute magnitude helps determine a body's geometric albedo.

• 3 JunoRelated: Juno’s absolute magnitude helps estimate its size and compare its intrinsic brightness with other asteroids.

• SN 1972ERelated: It expresses the intrinsic brightness that SN 1972E's observed flux must be calibrated against.
