Description

Messier 33 (M33, NGC 598, Triangulum Galaxy) is a magnitude 5.7 spiral galaxy in the constellation Triangulum. It is about 3 million light years from Earth and is the largest member of the Local group of galaxies which includes our own Milky Way. A good observer under pristine dark skies can see it visually but it is quite diffuse and can be difficult to see much detail through telescopes in more light polluted areas.
