Distant Space !!!

Light Years

What are Light Years

Light Years :
are another measurement for distance in space.
For Example :
would it be easier to say Proxima Centauri (the closest star to the earth other then the sun)
is 24,690,000,000,000 miles away or would it be easier to say Proxima Centauri in 4.2 light years away.

Light Years in space

Most objects in space are so far away, that using a relatively small unit of distance, such as an astronomical unit, is not practical. Instead, astronomers measure distances to objects which are outside our solar system in light-years.
