10,000 km 10,000,000 km the distance light can travel in 10 years ten times the distance from Earth to the Sun
I gave my students this multiple choice question: How far from Earth is an object that is 10 light years from Earth?

Only one answer is correct among these 4 choices:
- 10,000 km
- 10,000,000 km
- the distance light can travel in 10 years
- ten times the distance from Earth to the Sun

Could you tell me which one is correct?

the distance light can travel in 10 years
