why is the distance between stars expressed in light years? what do you understand by the statement that a star is eight years away from the earth
Answers
Explanation:
The distance between the stars and the earth is zillions of kilometers, and they are practically very far from the earth. The large distances are uttered in light years, which is a distance and is measured on the travelling speed of light. Therefore, this means that the distance between the star and the Earth is equal to the remoteness toured by light in the eight years. You can further discuss the same with your friends or teacher in case you have any doubt.
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.
