Why is the distance between stars expressed in light years? What do you understand by the statement that a star is eight light years away from the Earth?
Answers
Answer:
Hence 8LightYears, means distance traveled by light in 8 years.
Explanation:
One light year is a unit of distance that is travelled by Light in one year.
Light is known to be the fastest travelling entity. And hence the distance is measured in light years, because such distances are huge.
Answer:
distance between stars is expressed in light years as astronomical objects like such are very far off from earth and giving their distance in km can be inconvenient. Light year is a large unit and tells about the distance travelled by light therefore, large distances are expressed in light years.
a star is located 8 light-years away from the earth, it means that the distance between the star and the earth is the distance light would travel in eight years.
