Answer 2

Answer:

Hence, the large distances are expressed in light-years. If 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. So, the distance between the earth and star = 8 ✕ (9.46 ✕ 1012) = 7.6 ✕ 1013 km.
