]The diagram below shows the location of three stars in space. Three stars in space, Star 1 is on the far left, Star 2 is to it's right, Star 3 is to the left of Star 2, the distance between Star 2 and Star 3 is little further than the distance between Star 1 and Star 2. The light from Star 2 reaches Star 1 in 63 years. If Star 3 is 75 light years from Star 2, which of these conclusions about the stars is correct? Star 2 is 75 miles away from Star 3. Star 2 is 63 kilometers away from Star 3. Star 1 is 12 light years away from Star 3. Star 1 is 138 light years away from Star 3.
