HD 75898 is an 8th magnitude star approximately 255 light-years away in the constellation Lynx. The star is 28% more massive, 60% larger, and 3 times as luminous as the Sun. It is a metal-rich star, with 186% the solar abundance of iron. In 2007 the California and Carnegie Planet Search team found one planet orbiting HD 75898.[2]

Nomenclature
In 2019 the HD 75898 system was chosen as part of the NameExoWorlds campaign organised by the International Astronomical Union, which assigned each country a star and planet to be named. HD 75898 was assigned to Croatia. The winning proposal named the star Stribor, after the god of winds in Slavic mythology, and the planet b Veles, after a deity of earth, water and the underworld in Slavic mythology.[6]

Planetary system
The planet HD 75898 b was discovered by the radial velocity method in 2007.[2] At the time the centre of mass of the system appeared to be accelerating, indicating the presence of a third, more distant, component at least the mass of Jupiter. Later additional monitoring however indicated that this long-period signal was likely a result of long-term magnetic activity on the parent star.[4]
However in 2024, an additional long-period planet, HD 75898 c, was confirmed using both astrometry and radial velocity, in addition to an intermediate-period activity cycle. Both planets are super-Jupiters, with planet c having a mass 8.5 times that of Jupiter, and planet b having a minimum mass 2.5 times that of Jupiter, with a likely true mass of about 6 Jupiters if coplanar orbits are assumed.[3]
