HD 35759 is astar with an orbitingexoplanet located in the circumpolar constellationCamelopardalis. With an apparent magnitude of 7.74, it's impossible to see with theunaided eye, but can be seen with binoculars. The distance to this system is 232 light years based onparallax measurements,[2] and it is drifting closer with a heliocentricradial velocity of −12.6 km/s.[5]
This is aG-type star with 15% more mass than theSun, but has 1.76 times the radius. It radiates at about 3solar luminosities, and has aneffective temperature of 5,927K, which gives it a yellow hue. HD 35759 is slightly enriched in metals, with having 9.6% more iron abundance than the Sun. Like many older G-type stars, HD 35759 rotates rather slowly, with aprojected rotational velocity of 3 km/s.
In 2016, asuper-jovian exoplanet was discovered orbiting the star on aneccentric orbit. Since the planet was discovered usingdoppler spectroscopy, its radius and true mass is unknown.
