Triangulum is one of the smallest constellations in the northern hemisphere. Its name means "triangle" in Latin. The brightest stars in Triangulum form a long triangle.
Triangulum Australe
Transit Date of principal star:
3 June
Triangulum Australe, "The Southern Triangle", is one of the few constellations which has an obvious asterism. It was introduced by Johann Bayer in 1603.
Triangulum, the Triangle, was recognized as a distinct constellation since ancient Greece.
Triangulum Galaxy (M33) is the true highlight of this small constellation.

Triangulum Minor, the lesser triangle:
An obsolete constellation that was created by the Polish astronomer Johannes Hevelius. It was formed from three dim stars found immediately below the constellation of Triagulum, towards Aries, the ram.
Triangulum Australe is the southern hemisphere counterpart of Triangulum. It is a bigger constellation and contains brighter stars than Triangulum and it never sets for most of Australia.

The nearest large galaxy cluster, the Virgo Cluster, is about 59 megalight-years away.
M33, the Triangulum galaxy, is like a miniature version of the Milky Way. It has a big bulge of stars in the center surrounded by bright spiral arms, dark dust lanes, and bright knots where new stars are being born.
This is the The Triangulum galaxy M33. Under good conditions it can be seen with the naked eye.

In 1924 Edwin Hubble detected Cepheids in the Andromeda nebula, M31 and the Triangulum nebula M33. Using these he determined that their distances were 900,000 and 850,000 light years respectively.
This contains around 70 galaxies with the big ones being our own Milky Way, the Andromeda Galaxy (M31), and the Triangulum Galaxy (M33).
Located in the constellation Triangulum, M33 is a member of our local group of galaxies. It is a spiral galaxy with a diameter of 60,000 light-years, which makes it much smaller than its neighbor, M31.

A projection of the possible orbit of the Triangulum galaxy around Andromeda, taken from the new study. Astronomers believe that Triangulum will eventually be absorbed by its neighbour, contributing to the ongoing formation of Andromeda.
The other galaxy (M33 in Triangulum) is much harder to see although it is at a similar distance to the Andromeda galaxy. This is because it is smaller and less bright intrinsically. It too is a spiral galaxy.
