The H-R diagram is the most important graph in astronomy. One of the reasons that this graph is so powerful is the number of different kinds of data it shows. Most graphs show two types of data. The H-R diagram shows at least 5. Can you name these 5 types of information about stars that appear on the H-R diagram?
We can see from the HR diagram, the five types of information appeared are:
1. Absolute magnitude or Luminosity
2. Effective temperature
3. Mass of star
4. Size of star ( radius )
5. Lifetime or Age of star
