HomeworkLab Analysis1. Label the ovals in the organizer below with “galaxy”,
“solar system”, “universe”, and “planet” to show their relationships to each other. (The ovals do not represent orbits.)
2. If you were to add “star” to the organizer above, where would you place it?
3. Explain why you would choose this location in the diagram.
