HD 143361 and Its Single Known Planet
HD 143361 is a star 223 light-years away with a spectral type of G6 V, placing it in the same broad temperature class as the Sun. It is host to one known planet, HD 143361 b. The star is estimated to be 5 billion years old, with a mass of 0.95 solar masses, a radius of 0.99 solar radii, and a temperature of 5510 K. Its reported temperature is cooler than the Sun's.
HD 143361 b was discovered in 2008 using 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. The planet's minimum mass is 1120 Earth masses, meaning its true mass is at least this value, and it is roughly 3.53 times Jupiter's mass. Its minimum mass is larger than Earth's. HD 143361 b completes one orbit in 1040 days.
