HD 190360 and Its Three Known Planets

HD 190360 is a star of spectral type G6 IV located 52.2 light-years away, and three planets have been reported orbiting it. The star's age is 6.7 billion years, its mass is 0.96 solar masses, its radius is 1.13 solar radii, and its temperature is 5590 K. Its mass estimate is smaller than the Sun's, its radius is larger than the Sun's, and its temperature is cooler than the Sun's.

HD 190360 b was discovered in 2003 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. Its mass is 537 Earth masses and its orbital period is 2890 days. Among the listed planets, it has the largest reported mass and the longest year.

HD 190360 c was discovered in 2005, also by radial velocity. Its mass is 26.2 Earth masses and its orbital period is 17.1 days. Among the listed planets, it has the second-smallest reported mass and the shortest year.

HD 190360 d was discovered in 2026 by radial velocity. Its mass is 11.9 Earth masses and its orbital period is 88.7 days. Among the listed planets, it has the smallest reported mass and the second-shortest year.
