HD 285507 is a K4.5 V star located 147 light-years away. This host is known to have one planet. The star is 0.625 billion years old, with a mass of 0.734 solar masses and a radius of 0.656 solar radii. Its temperature is 4500 K, cooler than the Sun's, and both its mass and radius estimates are smaller than the Sun's.
The planet HD 285507 b was discovered in 2013 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 311 Earth masses, a lower bound on its true mass and larger than Earth's. The planet completes an orbit in 6.09 days.
