The sun is actually the closes at 93 million miles or 1 Astronomical Unit(A.U.) The closes other star is Alpha Centauri, which is actually part of the binary star system Proxima Centauri, it is 4.6 light years away. or the distance light travels in 4.6 years. To find the distance in miles figure out the amount of seconds in 4.6 years and multiply by 186,000.
