HD 141399 is a K-type subgiant 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}}. The star has very low starspot activity.

Planetary system

In 2014, four planets orbiting HD 141399 were discovered by the radial velocity method.{{citation|arxiv=1404.7462|year=2014|title=A Four-Planet System Orbiting the K0V Star Hd 141399|doi=10.1088/0004-637X/787/2/97|last1=Vogt|first1=Steven S.|last2=Butler|first2=R.
