20 Leonis Minoris is a binary star system in the northern constellation of Leo Minor.
[6] The system made its closest approach about 150,000 years ago when it came within 32.2 ly (9.86 pc).
[13] The primary member of this system is a G-type main-sequence star with a stellar classification of G3 Va Hδ1.
[11] A candidate exoplanet orbiting 20 Leonis Minoris A (HD 86728) was first detected in 2020,[15] and confirmed in 2024 as the first discovery of the NEID Earth Twin Survey (NETS).
With a minimum mass of 9.2 ME and an orbital period of 31 days, this is most likely a hot Neptune-type planet.
