What is the unit of measurement of the distance of stars from the earth?

1 astronomical unit
To measure the distance of a star, astronomers use a baseline of 1 astronomical unit (AU), which is the average distance between Earth and the sun, about 93 million miles (150 million kilometers).

What unit is used to measure the distance to other stars beyond the sun?

Many astronomers prefer to use parsecs (abbreviated pc) to measure distance to stars. This is because its definition is closely related to a method of measuring the distances between stars. A parsec is the distance at which 1 AU subtends an angle of 1 arcsec.

How far away is Proxima Centauri from the Sun?

Proxima Centauri is 4.3 light-years from the Sun. It is a dim red star in the constellation of Centaurus that lies at a distance of over 40 million million kilometers, some 270,000 times greater than the distance between the earth and the sun. The nearest stellar neighbors to the Sun are three stars that make up a multiple system.

What is the distance between stars measured in light years?
