Canis Major Dwarf Galaxy
The Canis Major Dwarf is an irregular galaxy. It may be the closest neighbouring galaxy to us in the Milky Way. It is about 25,000 light-years away from the Solar System, and 52,000 light-years from the Galactic centre. It has a roughly elliptical shape and is thought to contain as many stars as the Sag DEG, the previous contender for closest galaxy to us.
