Light Year is unit for all astronomic distances
AU is not used to measure the distances on earth, because a astronomical unit is a unit of measurement equal to the distance between Earth and Sun. So that's why you cannot use Au for measure the distances on Earth.
An Astronomical Unit is the distance between Earth and the Sun and is used as a measurement unit for measuring the distances of other objects from Earth.
We measure distances between celestial objects (such as suns, planets, and galaxies) by a unit of measurement called "AU" which stands for, Astronomical Unit. One AU is the equivalent to 93 million miles, which is roughly the distance from earth to the sun. Let's compare that to the next closest star to us, Alpha Centauri, which is 4.4 light years away, or about 271,930 AUs! Distances are Immense.
The distance between stars is typically measured in light years, which represents the distance that light can travel in one year. This unit is used because distances in space are vast and need a large unit of measurement.
The unit of measurement used to measure distances between galaxies is typically the light-year, which is the distance that light travels in one year. This unit is used because of the vast distances involved in intergalactic space.

The standard unit of measurement used in Liberia for determining distances and quantities is the metric system.
Kilometers
au
An astronomical unit (AU) is a unit of measurement used in astronomy that is equal to the average distance between the Earth and the Sun, about 93 million miles. A parsec is a unit of measurement used to describe astronomical distances, equal to about 3.26 light-years or 206,265 AU.

another unit for measuring distances is AU (Astronmical Unit)
Light years or parsecs
To measure the distance of stars you have to measure by light years.
An astronomical unit (AU) is a unit of measurement used in astronomy to describe distances within the solar system. One AU is roughly equal to the average distance from the Earth to the Sun, which is about 150,000,000 km.
Because it is a large number, suitable for large distances. Astronomers also like to use the unit Parsec.
