HD 168746 is a Sun-like star with a close orbiting exoplanet in the constellation of Serpens.
With an apparent visual magnitude of 7.95,[2] it is too faint to be viewed with the naked eye but is easily visible with binoculars or a small telescope.
The distance to this system is 136 light years based on parallax measurements, and it is drifting further away from the Sun with a radial velocity of 25.6 km/s.
The star is radiating a 4% greater luminosity than the Sun from its photosphere at an effective temperature of 5,637 K.[4] In 2019 the HD 168746 planetary system was chosen as part of the NameExoWorlds campaign organised by the International Astronomical Union to mark to 100th anniversary of the organisation.
The winning proposal named the star Alasia, an ancient name for Cyprus, and the planet Onasilos after an ancient Cypriot physician identified in the Idalion Tablet, one of the oldest known legal contracts.
