The diagram below shows the position of the sun and two galaxies, G1 and G2. The distance between the two galaxies is represented by Y. (3 points) The picture shows the sun and two ovals labeled G1 and G2 along a straight horizontal line. The sun is on the extreme left and G1 is on the right of the sun. G2 is on the right of G1. The distance between the sun and G2 is labeled as 600 billion km. The distance between the sun and G1 is labeled as 400 billion km. The distance between G1 and G2 is labeled as Y.
