The diameter of our disk-shaped galaxy, the Milky Way, is about 1.0 × 105 light-years (ly). The distance to the Andromeda galaxy (Fig. PI.57), which is the spiral galaxy nearest to the Milky Way, is about 2.0 million ly. If a scale model represents the Milky Way and Andromeda
galaxies as dinner plates 25 cm in diameter, determine the distance between the centers of the two plates.
