HD 141399 is a K-type main-sequence star 121 light-years away in the constellation of Boötes. Its surface temperature is 5602 K. HD 141399 is enriched in heavy elements compared to the Sun, with a metallicity Fe/H index of 0.36±0.03.[5] Its age is unknown. The star has very low starspot activity.[3]

## Planetary system[edit]

In 2014, four planets orbiting HD 141399 were discovered by the radial velocity method.[6] Planet HD 141399c is possibly located within the habitable zone.[3] The planetary orbits are close to high-order mean-motion resonance[7] and closely conform to Titius–Bode law. Two additional planets, one with a period of 462.9 days, are suspected by analogy with the orbits of the Solar System planets.[8] The planetary orbits around HD 141399 are expected to "jump" periodically on a timescale of a few million years between several quasi-stable configurations due to planet-planet interactions.[7] HD 141399 is one of only two known planetary systems consisting of at least four massive gas giants (the other is the system of planets around the young star HR 8799).[9]
