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 objects[edit | edit source]

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 clusters[edit | edit source]

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

Satellite galaxies[edit | edit source]

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.
