It was listed as entry number 34 in A Catalogue of Circumpolar Stars, published posthumously in 1838 by British astronomer Stephen Groombridge.

Gaia observations suggest a rotation period of 44 days and a magnetic activity cycle of roughly 9 years.

It is a red dwarf main sequence star that undergoes flare events like the primary; it has a spectral type M4.1,[3] so it also has a lower effective temperature.

[15] The planet's existence was deduced from analysis of the radial velocities of the parent star by the Eta-Earth Survey using HIRES at Keck Observatory.

To date, this is the fourth-closest confirmed multi-planet system to the Sun, hosting the longest-period Neptune-mass exoplanet discovered so far.
