[9] The absolute magnitude of this star is 5.25,[2] indicating it would have been visible to the naked eye at that time.
This is an ancient, thick disk population II[10][7] star with an estimated age of twelve billion years.
[6] X-ray emission has not been detected, suggesting a low level of coronal activity.
[11][12] The star is radiating 70% of the luminosity of the Sun from its photosphere at an effective temperature of 5,648 K.[5] A superjovian planetary companion was detected by the CORALIE team, based on observations beginning in 2003.
[13] An astrometric measurement of the planet's inclination and true mass was published in 2022 as part of Gaia DR3.
