It has an estimated mass between 10 and 40 billion solar masses. For this reason, Triangulum is one of the critical sky marks of the Bortle Dark-Sky Scale. Despite it’s size, the Triangulum Galaxy appears much dimmer than M31 – The Andromeda galaxy. (See below.) M33 - Triangulum Galaxy . Messier 33 or M33 (also designated NGC 598) is a spiral galaxy in the constellation Triangulum. The M33 Galaxy is the third-largest galaxy in the local-group of galaxies, behind the Milky Way and Andromeda. This suggests that the two galaxies have tidally interacted in the past. Photograph The Triangulum Galaxy. M33 lies at an estimated distance of 3 million light years. The Triangulum Galaxy. The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum.It is catalogued as Messier 33 or NGC 598.The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy.It is one of the most distant permanent objects that can be viewed with the naked eye.
M33 - Triangulum Galaxy . Messier 33 or M33 (also designated NGC 598) is a spiral galaxy in the constellation Triangulum. That’s half the diameter of the Milky Way.
A stream of hydrogen gas linking Triangulum to the Andromeda Galaxy was discovered in 2004 and confirmed in 2011. Also prominent in the local group is the Triangulum Galaxy (M33), Leo I, and NGC 6822. The Triangulum Galaxy Messier 33 (M33, NGC 598) is another prominent member of the Local Group of galaxies. M33 lies at an estimated distance of 3 million light years. Messier 33 occupies an area of 70.8 by 41.7 arc minutes in size and has a true diameter of about 60,000 light years, slightly more than a half of the Milky Way’s diameter. The Triangulum Galaxy captured during the Black Forest Star Party.. With a diameter of about 60,000 light-years, the Triangulum galaxy is the third largest member of the Local Group of galaxies, roughly 40% the size of the Milky Way. The Triangulum Galaxy (M33, NGC 598) is a nearby type Sc spiral galaxy that is a prominent member of the Local Group.With about half the diameter of the Local Group's two dominant systems, the Andromeda Galaxy and our own Milky Way, M33 is an averaged-sized spiral, with a mass of between 10 and 40 billion solar masses. The Pisces Dwarf, another galaxy in the Local Group, is located 913,000 light years from both galaxies and could be a satellite galaxy of either Triangulum or Andromeda Galaxy. The Triangulum Galaxy (M33) is a spiral galaxy in the constellation Triangulum, that is believed to be a satellite of the Andromeda Galaxy.Messier 33 can be seen visually with the naked eye under exceptionally good seeing conditions with no light pollution. It has an apparent visual magnitude of 5.7 and its angular diameter is 73x45 arc-minutes. It has an apparent visual magnitude of 5.7 and its angular diameter is 73x45 arc-minutes. With a diameter of about 60,000 light-years, the Triangulum galaxy is the third largest member of the Local Group of galaxies. There are over 30 galaxies that are considered to be in the local group, and they are spread over a diameter of nearly 10 million light years , with the center … Astronomers have estimated that Triangulum measures about 50,000 light-years across.

This galaxy is small compared to its big apparent neighbor, the Andromeda galaxy M31 , and to our Milky Way galaxy , but by this more of average size for spiral galaxies in the universe. Triangulum may be home to 40 billion stars, compared to 400 billion for the Milky Way, and 1 trillion stars for Andromeda.
