Welcome to 

the exoplanetarium of the Working Group Star Names.

In our exoplanetarium we present:
 * the modern star names and their (hi)stories
 * constellations and their real (hi)stories  
 * some teaching material for the astronomy of exoplanets 

Sorry, we currently don't accept name proposals; only naming campaigns do. These modern star names are given to (faint) host stars of exoplanets. For bright stars historical names from all over the world are collected and applied to stars according to scientific criteria.

Star Names

Some star names are historically developed, other take from indigenous cultures and some are totally artificial.



even if you think you know them, you still can learn something new here.


Our recorded talks
and public events

Some suggestions for historical experiments.
