M33, also known as the Triangulum Galaxy, doesn't have a widely recognized alternative name like some other celestial objects. However, it is occasionally referred to simply by its Messier catalog number, M33. As the third-largest galaxy in our Local Group, after the Milky Way and Andromeda, M33 is a spiral galaxy located in the constellation Triangulum.

It is a popular target for amateur astronomers due to its relatively large size and proximity, making it visible in dark skies with binoculars or a small telescope. The Triangulum Galaxy is a fascinating object of study, providing insights into the dynamics and evolution of spiral galaxies.
