The system is located at a distance of 20.4 light years based on parallax measurements, but is drifting closer to the Sun with a radial velocity of −1.4 km/s.
[4] This is an M-type main-sequence star, a red dwarf, with a stellar classification of M4.0V.
The chromosphere of this star is weakly active, causing starspots that vary the stellar luminosity as it rotates.
This would have a minimum mass about 30 times that of Earth and orbit with a period of about 450 days.
[7] This is a super-Earth or mini-Neptune (the discovery paper uses the term "sub-Neptune") with a minimum mass of 5.5 Earths and a period of 36 days, placing it within the habitable zone.
