HD 49674 b
HD 49674 b is an extrasolar planet[1] located approximately 134 light-years away in the constellation of Auriga, orbiting the star HD 49674. This planet was discovered orbiting the star in 2002. The planet is a gas 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 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]
