It is located at a distance of 30.9 light years based on parallax measurements,[1] and is drifting further away with a heliocentric radial velocity of 26.4 km/s.
[3] This is an M-type main-sequence star, sometimes called a red dwarf, with a stellar classification of M2V.
The star is radiating just 3.5% of the luminosity of the Sun from its photosphere at an effective temperature of 3,632 K. It is estimated to be around nine billion years old,[5] and is spinning slowly with a rotation period of 40 days.
[7] Radial velocity observations with the Hobby-Eberly Telescope (HET) showed a 10.24-day periodicity, which was interpreted as being caused by a planet.
In an independent study, observations with Keck-HIRES also failed to confirm the 10.24-day signal.
