About 25.4 cm. The Andromeda Galaxy is about 2.54 million light years from us. The Milky Way is about 100,000 light years across. So if 100,000 lights years equals 1 cm,â¦ then 2,540,000 / 100,000 = 25.4.
Even though it is the same age as the Milky Way, Hubble observations reveal that the stars in Andromeda's halo are much younger than those in the Milky Way. From this and other evidence, astronomers infer that Andromeda has already smashed into at least one and maybe several other galaxies.
