Properties

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 G-type stars, HD 35759 rotates rather slowly, with a projected rotational velocity of 3 km/s.

Planetary System

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