HD 49674 b, along with its parent star, was chosen as part of the 2019 NameExoWorlds campaign organised by the International Astronomical Union in which each country was assigned a star and planet to be named. The HD 49674 system was assigned to Belgium. The winning proposal named HD 49674 b Eburonia and the parent star Nervia, both after prominent Belgic tribes, the Eburones and Nervii respectively.[3]
