The relationship between a star's temperature and brightness was discovered independently around 1910 by Ejnar Hertzsprung and Henry Norris Russell. The relationship between these to parameters is depicted in a Hertzsprung-Russell diagram or H-R diagram.

Scientists classify stars by size based on their mass. Stars can be categorized as dwarf stars (like our Sun), giant stars, or supergiant stars, with the size increasing as the mass of the star increases. The classification can also include specific categories such as red dwarfs, white dwarfs, or blue giants, depending on additional characteristics.
The HR diagram compares the luminosity (brightness) of stars against their surface temperature or spectral type. This plot helps astronomers classify stars based on their intrinsic characteristics and evolutionary stages.

Scientists use color, size, brightness, and temperature to classify stars.

The three characteristic are temperature, size, and brightness.
Stars are classified by their color, temperatures, sizes, and brightness, it could also be by composition and radiation.Scientists classify stars by color, luminosity, and temperature.
Stars can be described by their temperature, size (diameter), brightness (luminosity), color, composition, and age. These characteristics help scientists classify and study stars in the universe.

Stars are classified by four different characteristics. Apparent magnitude (brightness) and absolute magnitude (how bright it would appear at 10 parsecs from the earth). Luminosity, another measure of brightness, compares the star to the sun's brightness. Spectral classifications are measured by the star's temperatures. Finally stars are signed a number by scientists through the Morgan-Keenan System.
The surface temperature and the absolute magnitude, which is the brightness of the star when viewed from a standard distance of 10 parsecs.
The four variables astronomers use to classify stars are temperature, luminosity, size or radius, and mass. By analyzing these properties, astronomers can determine a star's position on the Hertzsprung-Russell diagram and classify it into different spectral types and stages of stellar evolution.
