distance between the Sun and Earth distance between the Moon and Earth distance between two stars in the same galaxy distance between two planets in the same solar system
I gave my students this multiple choice question: Astronomers measure distances using very large units called light years. Which distance between celestial objects would most likely be measured in light years?

Only one answer is correct among these 4 choices:
- distance between the Sun and Earth
- distance between the Moon and Earth
- distance between two stars in the same galaxy
- distance between two planets in the same solar system

Could you tell me which one is correct?

distance between two stars in the same galaxy
