un Discussion​

Answer 1

Answer:

Many astronomical objects like stars or galaxies are very far away from the earth & giving their distances in the kilometres unit becomes very inconvenient. Light-year is a large unit and equals the distance travelled by light in one year. Hence, the large distances are expressed in light-years.

Answer 2

Answer:

Because the distance between two stars is insanely far that's why they use light years. A light year is the distance light travels in a year (9.46 trillion km

which is 9,460,000,000,000 km)
