IAU-Catalog of Star Names

This list is continuously updated and added to by the WGSN.

We use the following abbreviations: 

  • NEWC: NameExoWorlds Campaign. These were public naming campaigns where different IAU bodies collaborated for public outreach, and allowed public name suggestions. Up to now, these campaigns had either a theme (e.g. “IAU 100” for the centenial) or/and criteria for the suggestion (e.g. in 2019 one suggestion per UN-registered nation). 
  • the abbreviations “sci-A” and “ind-A” are a quotation from Kunitzsch and Smart (2006) that we do not find acceptable; we only quote their wording. 
  • ASE is the newly founded “All Skies Encyclopaedia”, a project designed for the documentation of all historical and Indigenous names (no matter whether or not they are reflected in this catalog). It also has the full documentation of all the names we applied from 2024 on. We will provide the hyperlink late in 2025 as this project is currently preliminarily hosted (by a university). 

Acknowledgements

  1. Collecting the etymologies of star names was a key project of WGSN 2018-’24; then, we had a “Task Group Etymologies” coordinated by Doris Vickers (Austria) and contributed to by many WGSN-members. Its task was merely collecting information on origins and references for the names adopted in the previous years. 
  2. In 2024, we launched a new project (ASE) to collect and publicly document this type of information while discussing name suggestions. Then, all historical and Indigenous names will be automatically accurately documented, and also the reasons for adoption or rejection for this catalog.
