how far is the nearest galaxy from the milky way?
The closest spiral galaxy is Andromeda, a galaxy much like our own Milky Way. It is 2.2 million light years away from us. Here is where you can find the answer. If you want a way to reference light years in kilometers here it is! One Astronomical Unit, or AU for short, is 150 million km. And in a single light year there is 63241.1 AU. And we have2.2 million light-years distance to Andromeda. 63241.1AU x 2,200,000ly = 139,130,420,000AU. 139,130,420,000AU x 150,000,000km = 2.0869563e+19
