Answer : Yes, distance measurements based on the speed of light used for objects in space.

Explanation :  A light year is measurement  of distance  that light travel in a one year.

In a one year light travels 9460000000000 kilometer.

We know that, speed of light is [tex]3\times10^{8}\ m/s[/tex]

and  time is 31536000 seconds in 1 year

so, distance = speed of light X time

Now, the light year is [tex]9.4608\times10^{15} meter[/tex]

Example : The nearest star to earth is about 4.3 light year away.
