Answer 2

Answer:

The stars are very far away from the Earth and it is not convenient to express such distances in kilo¬metres. Thus, such large distances are expressed in unit known as light year.

If we say that a star is eight light years away from Earth, it means that the light from star will reach the Earth in eight years.
