The disk of the Milky Way galaxy is about 1.0 ✕ 105 light-years (ly) in diameter. The distance from the center of the Milky Way to the center of the Andromeda galaxy is about 2.0 million ly.
Imagine a scale model where the two galaxies are represented by circular plates. If the plate representing the Milky Way has a diameter of 24 cm, what would be the distance between the centers of the two plates in meters?
