HD 114729 and Its Radial Velocity Planet
HD 114729 is a G0 V star 123 light-years away. The G-type classification makes it Sun-like in temperature class, and the trailing V marks it as a main-sequence dwarf. Its reported age is 10.5 billion years, its mass is 0.95 solar masses, its radius is 1.48 solar radii, and its temperature is 5780 K. The star's reported radius estimate is larger than the Sun's. One planet is known to orbit this host.
That planet, HD 114729 b, was discovered in 2002 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 114729 b has a minimum mass of 262 Earth masses, a lower bound on its true mass rather than an ordinary mass estimate. Its minimum mass is larger than Earth's. The planet completes one orbit every 1120 days.
