It is located at a distance of 120 light years from the Sun, as determined by parallax measurements, and is drifting further away with a radial velocity of 31.1 km/s.
[4] The star shows a high proper motion, traversing the celestial sphere at an angular rate of 0.302 arcsec yr−1.
[7] The spectrum of HD 216770 presents as a late G-type main-sequence star, a yellow dwarf, with a stellar classification of G9VCN+1,[3] where the suffix notation indicates anomalously strong band of CN.
The star is radiating 79% of the luminosity of the Sun from its photosphere at an effective temperature of 5,399 K.[5] In 2003 an exoplanet was announced orbiting it by the Geneva Extrasolar Planet Search team.
[2] As the inclination of the orbital plane is unknown, only a lower bound on the mass of the object can be determined.
