For the first time, in response to the public’s increased interest in being part of discoveries in astronomy, the International Astronomical Union (IAU) is organizing a worldwide contest to give popular names to selected exoplanets along with their host stars. The proposed names will be submitted by astronomy clubs and non-profit organisations interested in astronomy, and votes will be cast by the public from across the world through the web platform NameExoWorlds. This platform is under development by the IAU in association with Zooniverse. The intention is that millions of people worldwide will be able to take part in the vote. Once the votes are counted, the winning names will be officially sanctioned by the IAU, allowing them to be used freely in parallel with the existing scientific nomenclature, with due credit to the clubs or organizations that proposed them.
