HD 49674 b,formally namedEburonia,is anextrasolar planet[1]located approximately 134light-yearsaway in theconstellationofAuriga,orbiting thestarHD 49674.This planet was discovered orbiting the star in 2002. The planet is agas giantand 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 2019NameExoWorldscampaign organised by theInternational Astronomical Unionin 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 bEburoniaand the parent starNervia,both after prominentBelgictribes, theEburonesandNerviirespectively.[3]
