So far away that it is not meaningful to count the meters or the kilometers. So we count their distances in terms of the how much time light from the star takes to reach Earth. Light from the nearest star take 4 years to reach us, and light from some stars and galaxies takes millions and billions of years to reach Earth. Remember that light has the fastest speed in nature.
