Two units of distance used by scientists to describe distances in space are the light-year and astronomical unit. Why do scientists use the light-year instead of Astronomical Units to measure the distances between stars?
The speed of sound is too slow.
Telescopes can measure only in light years
Distant stars can only be seen if there is light
The smaller numbers that result from measuring with larger units are easier to use

The smaller numbers that result from measuring with larger units are easier to use.

Light year is a unit of astronomical distance that measures the distance traveled by light in one year. The distance between stars can also be measured using parsecs.

The equivalent of this distance in various units is written as follows;

  • 1 light year (ly) = 9.5 x 10¹² km = 63,240 AU
  • 1 parsec = 3.26 ly

Using light year to represent the unit of distance is more concise because big measurement can be represented easily with small numbers using this large unit.

Thus, we can conclude that the smaller numbers that result from measuring with larger units are easier to use.
