Question

what is a light year?how is it calculated?

Answer 1

HEY HERE IS YOUR ANSWER

The distances between stars across the universe are very great, so astronomers use light years as a larger unit than miles or kilometers. Tocalculate the actual distance of a light year, you simply need to multiply the speed of light by the number of seconds in a year....

a unit of astronomical distance equivalent to the distance that light travels in one year.A light year is the distance travelled by light in one year.

$\huge \boxed{calculation}$

Light year actually a measurement of a distance travelled by light during a period of 1 year..so called Light year...

We usually use light year to tell distances between stars...

1 light year = 9.5 × 10^15 meters

( See its unit, which is a meter...and we know that meter is used for distances...)
