Usually such distances are measured either in light-years, or in parsecs.

The distance to stars is measured in light years, which is the distance light travels in one year. The stars we see in the night sky are typically several light years away, with the closest star to Earth, Proxima Centauri, about 4.24 light years away.
The distance to stars is typically measured in light-years, which is the distance light travels in one year. Light-years are used because the distances to stars are vast and measuring in kilometers or miles would be impractical. For closer stars, distances can sometimes be measured in parsecs, which is another unit of distance based on trigonometric parallax.
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
