Astronomers classify stars.
Hertzsprung-Russell (HR) diagram classifies stars based on their luminosity (brightness) and temperature. This diagram allows astronomers to categorize stars into main sequence, giants, supergiants, white dwarfs, and other classes based on their positions in the diagram. It provides insights into the life cycle and evolutionary stage of stars.
The system that classifies stars according to their brightness is called the magnitude scale. This scale measures the apparent brightness of stars as seen from Earth, with lower numbers indicating brighter stars; for example, a star with a magnitude of 1 is brighter than one with a magnitude of 5. Additionally, the absolute magnitude scale measures the intrinsic brightness of stars at a standard distance of 10 parsecs. Together, these systems help astronomers categorize and compare stars based on their luminosity.

A taxonomist is a person who classifies things into kingdoms.
Stars are classified by their spectral characteristics and luminosity. Spectral classification categorizes stars based on their temperatures and composition, while luminosity classifies them by their brightness and size. These classifications help astronomers understand the characteristics and behaviors of different types of stars.
