Triangulum Galaxy

The Triangulum Galaxy, also known as M 33, is a spiral galaxy that is the third largest member of the Local Group, and the main galaxy the Celestia Worldbuilding Project is based in. It is 28,120 light-years in radius, containing around 40 billion stars and many H II regions with active star formation. Trianglum also has many sapient species and civilizations.

Notable objectsEdit

 
The Triangulum Galaxy in Celestia.
  • The galactic core region, including The Eye of Providence and the surrounding Providence Nebula, the Evolutionary Cross massive star cluster, and the bright supergiant star Meridan.
  • The Bora Molecular Cloud Complex, a large star-forming region surrounding the Wolf-Rayet star Bora. It also contains the Ronel system of three massive, luminous stars, and is near the very bright supergiant Casalis.
  • The Marcaide Cluster and its associated MCC, surrounding the Marcaide triple system and containing many luminous stars, including Genderen, a luminous blue variable, the Migatte binary system, Tovera, and the massive contact binary Viftis.
  • The Arcus Nebula, a very large nebula centered on the red giant star Arcus and the GASCA cluster group.
  • The Clash of Light and Darkness, also known as M33 X-7, a very massive X-ray binary system consisting of a black hole and an O-type giant star.
  • Lacrimosa, an exceedingly bright Wolf-Rayet star that is as of Release 15 both the most massive and most luminous star in CelWP, at 258 solar masses and nearly 9 million solar luminosities. It is surrounded by a nebula.
  • Add more if you want, but keep in mind that this list is for objects that are notable on a galactic scale (like large nebulae and very bright stars).

Globular clustersEdit

Triangulum has around 60 globular clusters, including the Sanctuary Cluster.

Satellite galaxiesEdit

Triangulum has several satellite galaxies, though less than larger spiral galaxies like Andromeda. These include the Pisces Dwarf, Eqien's Galaxy, and the Endurance Galaxy.
