HD 75898 b is an extrasolar planet approximately 263 light years away in the constellation of Lynx. This is a giant planet orbiting the star HD 75898. The minimum mass is two and a half times more than Jupiters, classifying it as a massive gas giant. Since the parent star is 3 times more luminous than the Sun, the planet puts it in the inner edge of the habitable zone with effective temperature of 312 K. The planet orbits at 1.168 AU from the star, taking 1.1 year to orbit in relatively circular orbit, about the same eccentricity as HD 70642 b and Mu Arae e.
