Triangulum, also known as Messier 33 (M33), is a spiral galaxy located approximately 3 million light-years from Earth in the constellation Triangulum. It is the third-largest member of the Local Group, which also includes the Milky Way and Andromeda galaxies. Triangulum is notable for its relatively low surface brightness and a rich population of stars, with a diameter of about 60,000 light-years. The galaxy has been a target for numerous astronomical studies due to its proximity and well-defined structure.
Triangulum: - Try-An-gou-lum
That doesn't make sense - there is not "a" triangulum galaxy, it is "the" triangulum galaxy. In other words, this is the proper name of one specific galaxy.
At least two constellations: Triangulum, and Triangulum Australe.
Triangulum is the constellation between Aries the Ram and Andromeda. It's also the name of a spiral galaxy - it's named The Triangulum Galaxy because it's found in the Triangulum Constellation.
The galaxy Triangulum is like the Milky Way and Andromeda galaxies a Spiral Galaxy
It is spiral barrered
The name tells us that it is in the Triangulum constellation. That indicates the general direction. Also, the Triangulum Galaxy is approximately 3 million light-years away - fairly close for a galaxy. In other words, it is part of the Local Group.
