The Great Succession Crisis

  Object name: Objects (primarily planets and moons) are named by their position in their star system. Planets are named numerically (Primus, Secundus, Tertius, Quartus, Quintus, Sextus, Septimus, Octivus, Nonus, Decimus, etc.). Moons are designated first by their planet location, then numbered, started with the closest moon to the planet. For example, D425E25 Quintus has sixteen moons large enough to be classified as moons (dwarf objects such as asteroids are not named). The nearest of these moons is therefore named D425E25 Quintus Primus whereas the most distant of these moons is named D425E25 Quintus Sextus-Decimus.

  Dwarf objects, asteroid fields, rings, and other features are designated by the object they rotate around. For example, the asteroid field between D425E25 Tertius and D425E25 Quartus is named simply D425E25 Luanxing (pebble of the star) whereas the ring system around D425E25 Sextus is called D425E25 Sextus daixing (ribbon of the stars).
