Like our own galaxy, or M31, the Andromeda galaxy, M33 is part of the "Local Group", "our" galactic group.
It is 3 million light-years away and is the most distant object visible to the naked eye; however this requires an excellent observatory site and very good eyesight to see a very dim white spot.
The galaxy is most spectacular when seen through binoculars, because of its size (over twice the diameter of a Full Moon) and its low surface brightness which makes it visually disappointing through a telescope.
