Incomplete The closest star, other than the sun, to earth is Alpha Centauri, which is 2.57 x 1013 miles from earth. The farthest star that can be seen with the naked eye is V762 Cas which is 9.57 x 1016 miles from earth. Suppose you discovered a star that was 6.45 x 1016 miles from earth. If the speed of light is 2.999 x 10 m/s, how many years would it take light from the star to reach earth? Time for light to reach earth years
