If it is a main sequence star, then it is most likely a red dwarf with about half of the mass of the Sun. Other possibilities are a white dwarf star, or (less likely) a neutron starorblack hole.[1]
In 2006, an Uranus-mass extrasolar planet was detected by gravitational microlensing around this star.[2]
