Closet galaxy to the milky way galaxy?
The nearest known is the very small Canis Major Dwarf Galaxy at 25,000 light years, a 'satellite' galaxy that orbits the Milky Way. This was only discovered in 2003, so there may be an unknown small galaxy closer. If you want the closest galaxy that is not a Milky Way satellite, that seems to be NGC 185 at just over 2 million light years, though this is in turn a satellite of the Andromeda Galaxy (M31). Finally, M31 is the nearest galaxy that is anything like the Milky Way, a large spiral with its own satellites. It's about 2.5 million light years away.
