The Triangulum Galaxy (M33) is about 2.7 million light-years away, and is estimated to contain around 40 billion stars. This makes it the smallest of the three large galaxies in our local group, after Andromeda and our Milky Way. Measuring about 60,000 light-years across, it is thought to be the farthest object visible to the naked eye.
