Stars are not measured in light years. The distance between them is.

Light years or Parsecs
because the stars are very far away so the astronomers use light years
Usually such distances are measured either in light-years, or in parsecs.
usually the space is measured in light years
because the stars are very far away so the astronomers use light years
Distances to stars are mainly measured in PC (Parsecs). Light years are also used because the distances covered are so great. For example. Proxima Centauri our nearest neighbourhood star is: Light years: 4.23 Parsecs(PC): 1.3009. If we used miles then the distance would be: 24,866,054,200,000 or kilometers 40,018,035,200,000 Which one is the easiest to remember and that is your answer
They are measured in light years. Galaxies are often 100,000 light years across or more.
They are so far away that the light they emit takes many years to get here. Distances that large are measured in light years. A light year is the distance that light travels in one mean earth year.
