The IAU's names for exoplanets – and on most occasions their host stars – are chosen by the Executive Committee Working Group (ECWG) on Public Naming of Planets and Planetary Satellites, a group working parallel with the Working Group on Star Names (WGSN). [1] Proper names of stars chosen by the ECWG are explicitly recognised by the WGSN. [1]
Many of the names chosen were based on world history, mythology and literature. [3] In June 2019, another such project (NameExoWorlds II), in celebration of the organization's hundredth anniversary, in a project officially called IAU100 NameExoWorlds, [ 4 ] [ 5 ] welcomed countries of the world to submit names for exoplanets and their host stars .

For exoplanets orbiting a single star, the name is normally formed by taking the name of its parent star and adding a lowercase letter. A provisional IAU-sanctioned standard exists to accommodate the naming of planets that orbit two stars, which are known as circumbinary planets. A limited number of exoplanets have IAU-sanctioned proper names.
Currently, the responsibility for naming minor planets lies with the Working Group Small Bodies Nomenclature (WGSBN, originally the Committee Small Bodies Nomenclature, CSBN, and before that the Minor Planet Names Committee, MPNC), which is composed of 15 members, 11 of whom are voting members, while the other four are representatives for the ...
As minor planet discoveries are confirmed, they are given a permanent number by the IAU's Minor Planet Center (MPC), and the discoverers can then submit names for them, following the IAU's naming conventions. The list below concerns those minor planets in the specified number-range that have received names, and explains the meanings of those names.
