HD 185269 and Its Orbiting Planet
HD 185269 is a G0 star located 170 light-years away. It is a single planet-host within a system that includes three cataloged stars, and its measured properties are markedly larger and hotter than the Sun's. Its mass is 1.29 solar masses, its radius is 1.76 solar radii, and its temperature is 6060 K. The star's age is 3.4 billion years.
One planet is known to orbit this host: HD 185269 b. It was discovered in 2006 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. This planet completes an orbit in 6.84 days. Its minimum mass is 321 Earth masses, placing it well above Earth in mass and making it a lower bound on the planet's true mass rather than a fixed estimate.
