| A large celestial body that is composed of gas and that emits light; the sun is a typical star. | Star |
| The brightness of a star as seen from Earth. | Apparent magnitude |
| A measure of how bright a star would be if it were seen from a standard distance. | Absolute magnitude |
| A large cloud of gas and dust in interstellar space; a region in space where stars are born. | Nebula |
| A small, hot, dim star that is the leftover center of an old sunlike star. | White dwarf |
| A gigantic explosion in which a massive star collapses and throws its outer layers into space. | Supernova |
| A star that has collapsed under gravity to the point that the electrons and protons have smashed together to form neutrons. | Neutron star |
| A graph that shows the relationship between a star’s surface temperature and absolute magnitude; Hertzsprung-Russell diagram | H-R diagram |
| The location on the H-R diagram where most stars lie; it has a diagonal pattern from the lower right (low temp. and luminosity) to the upper left ( high temp. and luminosity). | Main sequence |
| The actual brightness of an object such as a star. | Luminosity |
