Exoplanet Archivedata

HD 35759 is a star with an orbiting exoplanet located in the circumpolar constellation Camelopardalis. With an apparent magnitude of 7.74, it's impossible to see with the unaided eye, but can be seen with binoculars. The distance to this system is 232 light years based on parallax measurements,[1] and it is drifting closer with a heliocentric radial velocity of −12.6 km/s.[5]

This is a G-type star with 15% more mass than the Sun, but has 1.76 times the radius. It radiates at about 3 solar luminosities, and has an effective temperature of 5,927 K, 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 a projected rotational velocity of 3 km/s.

Planetary System

In 2016, a super-jovian exoplanet was discovered orbiting the star on an eccentric orbit. Since the planet was discovered using doppler spectroscopy, its radius and true mass is unknown.
