Within the framework of its 100th anniversary commemorations, the International Astronomical Union (IAU) had organized the IAU100 NameExoWorlds global campaign that allowed any country in the world to give a popular name to one planetary system, comprising an exoplanet and its host star.

More than 110 countries - including Bosnia and Herzegovina - had organized national campaigns and proposed two names, one for the star and one for the exoplanet orbiting that star. Each nation’s designated star is visible from that country, and sufficiently bright to be observed through small telescopes.

A total of 360,000 proposals have been submitted and approximately 420,000 people voted.

Bosnia and Herzegovina has been assigned planetary system in the Aquarius constellation in which the extrasolar planet HD 206610b is orbiting the K-type star, named HD 206610.

An extrasolar planet, or exoplanet, is a planet outside the Solar System. K-type stars are orangish stars that are slightly cooler than the Sun.

The Steering Board of the IAU100 NameExoWorlds global campaign had to choose among three proposals submitted by the National Committee for Bosnia and Herzegovina, and eventually decided that the star HD 206610 will be named ‘Bosona’, while the exoplanet HD 206610b will be named ‘Naron’.

Bosona is the name given to the territory of Bosnia in the 10th century. Later, the name was transformed into Bosnia originating from the name of the Bosna River.

Naron is one of the names given to the Neretva River in Herzegovina in antiquity originating with the Celts who called it Nera Etwa, which means the Flowing Divinity.
