Question

1. Why is it convenient to express the
distance of stars in terms of light year
(or) parsec rather than in km?​

Answer 1

Answer:

because they are very far so we cannot measure distance in small uni

Answer 2

Answer:

Because it's the simple way to express the distance between stars ...

1 light year means 9.461 × 10^12 km...

1 parsec means 3.26 light years
