Question 1:
Why are A.U. and ly used to determine the distance between planets and the Sun in the solar system?
Answer:
A.U. and ly are used because the distance of the planets in the solar system is too great and can reach up to millions of kilometres. Therefore, relative units such as A.U. and ly are used so that the numbers in the calculation of distance between planets would not be too big.
