Triangulum Galaxy

Triangulum Galaxy, also known as Messier 33 or NGC 598, is an unbarred spiral galaxy (SA(s)cd) and possibly a satellite galaxy of the Andromeda Galaxy. It is located in the constellation of Triangulum, 2.73 million light-years away. It is one of the few galaxies that can be seen with the naked eye, visible as a fuzzy patch in a dark and clear sky. With an approximate diameter of 60,000 light-years, it is the third-largest member of the Local Group of galaxies, after after the Andromeda Galaxy and the Milky Way, and the smallest spiral galaxies in the Local Group.
