The distances between stars and between galaxies are enormous. Using more conventional units such as miles and kilometers gives you very large numbers in the trillions and higher. A light year, the distance light travels in a year, is far more useful. Stars that are in the same general neighborhood are usually a few light years apart. The nearest star to our sun, for example. is just over 4 light years away.
