HD 117207 and Its Planet
HD 117207 is a star 106 light-years from Earth with one known planet. Its spectral type, G7 IV-V, indicates a star of the same broad temperature class as the Sun, and its reported temperature of 5620 K is cooler than the Sun's. The star's reported radius of 1.11 solar radii is larger than the Sun's, while its mass is 1 solar mass and its age is 6.5 billion years.
The planet HD 117207 b was discovered in 2004 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 117207 b has a minimum mass of 612 Earth masses, a lower bound on its true mass, and is roughly 1.93 times Jupiter's mass. Its minimum mass is larger than Earth's. The planet completes an orbit every 2620 days.
