Welcome to exopla.net 

the exoplanetarium of the IAU-Working Group on Star Names presents:
 * the IAU-Catalog of Star Names (CSN) & their etymologies
 * the 88 constellations and their real (hi)stories  
 * information about our group, work process & backgrounds

Themes

FAQ3: Our IAU-Catalog of Star Names (CSN) is a living document; it is continuously updated after regular (roughly monthly) group meetings.


Export options are given above the table.

FAQ1: Sorry, we currently don’t accept name proposals; only naming campaigns do. Modern invented star names are given to (faint) host stars of exoplanets. For bright stars, we collect and apply historical names from all over the world according to scientific criteria.

FAQ2: In research papers, please kindly use only the names from the IAU-CSN. For aspects of education and heritage preservation, we are developing name-resolvers and an encyclopaedia to keep track of all cultural names per star.
Export options are given above the table.

FAQ4: The IAU doesn’t name stars after people. There are only ~9000 visible stars but billions of people on Earth (alive or passed). For dear ones, please remember that someconstellation names were created to represent love. Outstanding people could be honoured by naming a minor planet  or a feature on the Moon after them (IAU WGPSN and WGSBN, Commission B2).

Star Names

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

Constellations

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

Exoplanet Names

The IAU-Catalog of Exoplanet Names stems from the
