HD 49674 b, formally namedEburonia, is anextrasolar planet[1] located approximately 134light-years away in theconstellation ofAuriga, orbiting thestarHD 49674. This planet was discovered orbiting the star in 2002. The planet is agas giant and orbits extremely close to its star, which takes only 4.95 days to revolve.[2]
HD 49674 b, along with its parent star, was chosen as part of the 2019NameExoWorlds campaign organised by theInternational Astronomical Union in which each country was assigned a star and planet to be named. The HD 49674 system was assigned toBelgium. The winning proposal named HD 49674 bEburonia and the parent starNervia, both after prominentBelgic tribes, theEburones andNervii respectively.[3]
