HD 75289 and Its Solitary Known Planet
HD 75289 is a G0V star 95 light-years away, a Sun-like dwarf with one known planet in its cataloged system. The radial velocity method, which measures the wobble a planet's gravity induces in its star's motion, revealed HD 75289 b in 1999.
HD 75289 b has a minimum mass of 156 Earth masses, meaning its true mass is at least that great, and orbits in 3.51 days. Its minimum mass is larger than Earth's.
The host star is 3.28 billion years old, with a mass of 1.19 solar masses, a radius of 1.28 solar radii, and a temperature of 6100 K. Its mass and radius estimates are larger than the Sun's, and it is hotter than the Sun.
