M 33 or the Triangulum Galaxy at only 3 million light years away, is the third biggest galaxy in our local group of galaxies. It is a smaller spiral galaxy with a size of 60,000 light years across compared to M 31's 220,000 light years size. Furthest distance object that is capable of being seen with only the eye, although it would take clear and dark skies to see it. Probably first recorded by Giovanni Battista Hodierna in 1654. Compiled by Charles Messier in his catalog in 1771.
