distance between Earth and the Sun time of rotation of the nearest galaxy time in orbit of a satellite around Earth distance between the Sun and the nearest star
I gave my students this multiple choice question: A scientist studying outer space makes a calculation of 4.3 light-years. What does this calculation most likely represent?

Only one answer is correct among these 4 choices:
- distance between Earth and the Sun
- time of rotation of the nearest galaxy
- time in orbit of a satellite around Earth
- distance between the Sun and the nearest star

Could you tell me which one is correct?

distance between the Sun and the nearest star
