HD 175541 and Its Planet

HD 175541 is a star 423 light-years away with a mass of 1.65 solar masses, a radius of 3.8 solar radii, and a temperature of 5060 K. Its spectral type is G8 IV, and it is 1.9 billion years old.

One planet orbits this host. HD 175541 b was discovered in 2007 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion, with repeated wobbles revealing the planet and its orbital period. The planet has a minimum mass of 190 Earth masses and an orbital period of 298 days. Its minimum mass is a lower bound on its true mass and is larger than Earth's.
