Which galaxy is closest to ours?

The nearest big spiral galaxy to our galaxy, the Milky Way, is the Andromeda galaxy. Appearing as a smudge of light in the constellation Andromeda, this galaxy is about twice as big as the Milky Way. It is about 2.3 million light years away from us, although its vast size and luminosity make it visible to the naked eye. In fact, it is the most distant object that can been seen from Earth without a telescope.
