How Are Stars Classified?
Stars are classified based on their visual traits, like colour, and physical traits, like size and mass. Star classification is a way to categorize stars, either based on their color and/or size and mass. Since stars have so much variety in between them, classifying stars allows astronomers to find a star with certain characteristics much easier. Astronomers also classify stars in order to better understand the different types of stars in both our galaxy and our universe.
