[8] The star is too faint to be visible to the naked eye, having an apparent visual magnitude of 8.70.
The star is drifting further away with a radial velocity of +26 km/s, having come as close as 52.9 light-years some 1.2 million years ago.
However, in 2011 Dumusque and colleagues found a class of K0/K1V, suggesting it is instead a K-type main-sequence star.
Radial velocity studies indicate that it has a planet, originally named HD 137388 b (mass 0.223 MJ, period 330d).
It orbits at a typical distance of 0.89 AU with an eccentricity of 0.36,[4][9] completely overlapping the star's habitable zone.
