Stars in the sky can appear brighter or dimmer than each other based on the star’s luminosity and ________ from the Earth. A star’s ________ is how bright the star appears from Earth, while a star’s ________ is the actual brightness of a star, also called luminosity.H-R diagrams demonstrate the relationship between a star’s absolute magnitude/luminosity and ________. For main sequence stars, as the star’s temperature increases, so does its absolute magnitude.

Stars in the sky can appear brighter or dimmer than each other based on the star’s luminosity and distance from the Earth. A star’s apparent magnitude is how bright the star appears from Earth, while a star’s absolute magnitude is the actual brightness of a star, also called luminosity.

H-R diagrams demonstrate the relationship between a star’s absolute magnitude/luminosity and surface temperature. For main sequence stars, as the star’s temperature increases, so does its absolute magnitude.

Explanation: Apparent magnitude refers to how bright a star seems from our perspective on Earth, while absolute magnitude provides a measure of its intrinsic brightness regardless of distance. H-R diagrams plot stars based on their temperature and luminosity, showing that hotter stars tend to be intrinsically brighter.
