If I remember all of my astronomy classes correctly, the unit of measurement between Earth and the Sun is 1 A.U., or Astronomical Unit, which is equal to 93 million miles. 1 light year is equal to 5,865,696,000,000 miles (9,460,800,000,000 km). Astronimical Units are used to measure distance within our own galaxy. To measure the distance between stars and galaxies, the unit is called a parsec (PC). 1 PC = 3.26 light years. Hope this helps!
. . they are a convenient unit. Another convenient unit is the parsec.
light years
A stellar unit refers to a unit of distance used in astronomy to measure the distance between stars. It is typically equivalent to the mean distance between stars within a galaxy, which can vary depending on the galaxy being observed.
Angstroms
Meters or kilometers, depending on the distance.
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.

Kilometres or miles
The unit used to measure the annual parallax of a star is parsecs. It is a unit of length that is equivalent to about 3.26 light-years, and it is commonly used in astronomy to describe distances to stars and galaxies based on their parallax angle.
Volts
The Astronomical unit is used to measure the large distances in our solar system. It is roughly the average distance between the Earth and the Sun.
