HD 177565 and Its Planet
HD 177565 is a G8V star located 55.2 light-years from Earth. This makes it a Sun-like main-sequence dwarf. Its age is 6.88 billion years, and it has a mass of 0.97 solar masses, a radius of 0.99 solar radii, and a temperature of 5650 K. Its reported mass, radius, and temperature are all smaller or cooler than the Sun's.
One planet is known to orbit this star. HD 177565 b was discovered in 2017 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 15.1 Earth masses, larger than Earth's, and an orbital period of 44.5 days.
