Size, color and temperature.
size
you classify stars by color, temperature, size, composition, and brightness.

Astronomers classify stars.
In Astronomy stars can be classified by theircolor (temperature)composition (as found by their spectrum)agelocation in a galaxymassproximity to other stars
Three characteristics to classify stars are their luminosity, size, and color or surface temperature.
age, brightness , color, bubblyness, yellowness , and heet
The three characteristic are temperature, size, and brightness.
you dont. sciensists never use age to classify a star
The first variable that is used to classify stars is its ionization state which can measure the photosphere's temperature and density. This information is gathered by splitting the light from a star with a prism and observing the resulting spectrum that includes absorption lines. Luminosity is another variable used; it is based on the width of absorption lines.
yes
Scientists use color, size, brightness, and temperature to classify stars.
