They are classified by the amount of Light they give off, and their temperature.
The HR diagram, also known as the Hertzsprung-Russell diagram, depicts the relationship between the luminosity and temperature of stars. It shows how stars are distributed in terms of their brightness and temperature, allowing astronomers to classify stars based on these characteristics.
The two characteristics of a star plotted on the Hertzsprung-Russell diagram are luminosity (brightness) on the y-axis and temperature or spectral type on the x-axis. This diagram helps astronomers classify stars according to their different stages of evolution.
Spectral class: Stars are classified based on the elements present in their spectra. Luminosity: The total amount of energy a star emits per unit of time. Temperature: Determines the color of the star and influences its brightness. Size: Stars can range from small, dense white dwarfs to giant supergiants. Age: The stage of life the star is in, from formation to death, affects its characteristics.
By spectral type: Stars can be classified based on their spectral characteristics, which provides information about their temperature, color, and composition. By luminosity: Stars can be categorized by their brightness, which can vary greatly based on their size and energy output. By evolutionary stage: Stars can be classified based on where they are in their life cycle, such as main sequence stars, red giants, white dwarfs, etc.
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.

Their Color!(:
The temperature of stars is indicated by their color, with cooler stars appearing more red and hotter stars appearing bluer. The brightness of stars is measured in terms of luminosity, which is the total amount of energy emitted per unit of time.
A star's temperature is indicated by its color, with hotter stars appearing blue and cooler stars appearing red. Brightness is measured using the star's apparent magnitude, with higher magnitudes representing dimmer stars and lower magnitudes representing brighter stars.
well as you can see the star is a hot burning thing that shines. it shines for billions of years. the stars temperature is to hot.
The brightness is very similar to the temperature, the brightness relies on the temperature
Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.
Size and temperature determine the brightness of stars.
by temperature, size, brightness, distance and color
Two ways are by temperature and brightness
