The Milky Way is the second-largest galaxy in the Local Group, with its stellar disk approximately 100,000 ly (30 kpc) in diameter, and, on average, approximately 1,000 ly (0.3 kpc) thick.
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.
