Kilometer [KM] = 1000 meters Megameter [MM] = 1000 Kilometers Gigameter [GM] = 1000 Megameters, 1.000.000 Kilometers Terameter [TM] = 1000 Gigameters, 1.000.000 Megameters, 1.000.000.000 Kilometers Petameter [PM] = 1000 Terameters, 1.000.000 Gigameters, 1.000.000.000 Megameters, 1.000.000.000.000 Kilometers Astronomical Unit [AU] = From the Sun to the Earth equals 1 AU (150 Gm) The galaxy is a large place.
