List of dwarf planet add-ons

This article lists all celestial body add-ons, which are no planet add-on or small body add-ons.

The International Astronomical Union (IAU), the official scientific body for astronomical nomenclature, defines a "dwarf planet" as a celestial body within the Solar System that satisfies these four conditions:

• is in orbit around the Sun
• has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (near-spherical) shape
• has not cleared the neighbourhood around its orbit
• is not a satellite

As Orbiter allows alternative star systems, these rules can also be applied to objects outside our solar system (replacing Sun with the respective alternative star)
