BD+20 594 and Its Neptune-Like Planet

BD+20 594 is a G-type star 585 light-years away, and it hosts one known planet. The star is estimated to be 3.34 billion years old, with a mass of 0.961 solar masses and a radius of 0.928 solar radii. Its temperature is 5770 K. Both the reported mass and radius estimates are smaller than the Sun's.

The planet, BD+20 594 b, was discovered in 2016 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. It is a Neptune-like planet, a size class that reaches 4 times Earth's radius. Its radius is 2.58 Earth radii, larger than Earth's, and its mass is 22.2 Earth masses, also larger than Earth's. Its mean density is 7.15 g/cm³, 1.3 times Earth's.

BD+20 594 b completes an orbit in 41.7 days.
