Question

Name the unit which is used to express distances between the various celestial bodies (like stars and planets)

Answer 1

Answer:

astronomical unit

Explanation:

This is a big number, and so astronomers use the astronomical unit to describe this distance. One astronomical unit, or 'au', is the distance between the Earth and the Sun. It is used to compare the distances of other bodies in the Solar System, such as the Sun, the planets, comets, and asteroids.
