Expert Answer:
The most commonly used units of distance are the light year, parsec and astronomical unit.
Astronomical Unit (A.U.)
Astronomical unit is usually used to measure distances within our solar system.
Light-Year (ly)
Most objects in space are so far away, that using a relatively small unit, such as an A.U., is not practical. To measure distances to objects which are outside our solar system, the unit used is light-years.
Parsec (pc)
Astronomers also use another unit of distance called a parsec (pc), which is equal to 3.26 light-years.
Note: We can convert to any other smaller unit as per the requirement.
