Hertzsprung-Russell Diagram showing star classifications
A scatter plot with surface temperature on the x-axis (from 30,000K to 3,000K) and luminosity on the y-axis (from 0.0001 to 100,000 solar units). Stars are plotted and color-coded by type: red for main sequence, orange for giants, blue for supergiants, and white for white dwarfs.

Main Sequence Red colored stars - hydrogen burning phase
Red Giants Orange colored stars - evolved giant phase
Blue Supergiants Blue colored stars - massive supergiant phase
White Dwarfs White colored stars - stellar remnants

Hertzsprung-Russell Diagram

The H-R diagram plots stars by their surface temperature (x-axis) and luminosity (y-axis). Most stars fall along the main sequence, where they spend most of their lives fusing hydrogen into helium.
