A Hertzsprung-Russell (HR) diagram is a tool that shows the relationships and differences between stars. For this assignment, follow these directions:

1. Print the data file so you have it handy and in front of you while you work.
2. Use the temperature and luminosity values to plot Group 1, Group 2, and Group 3 stars on a single HR diagram (plot values for stars in all three groups on the same plot) using the whiteboard below. Save your whiteboard as an image and insert it into your answer sheet. For more information on inserting your diagram into the answer sheet, follow these directions.
3. Answer the questions in complete sentences and submit the completed questions for grading.

Submit your completed project (your diagram and the answers to the questions) to the Project: HR Diagramsassignment link for grading. For information on how your project will be graded, see the HR Diagrams Rubric.
