'''16 Lyncis''' is a star in the constellation Lynx. It is positioned next to the western constellation border with Auriga, and is also known as '''Psi<sup>10</sup> Aurigae''', which is Latinized from ψ<sup>10</sup> Aurigae. The star has a white hue and is visible to the naked eye with an apparent visual magnitude of 4.90.<ref name=hr/> The distance to this object is approximately 241<ref name="van Leeuwen 2007"/> light-years based on parallax, but it is drifting closer to the Sun with a radial velocity of −12 km/s.<ref name="Gontcharov 2006"/> It has an absolute magnitude of 0.56.<ref name=Anderson2012/>
This object is a solitary<ref name=Eggleton2008/> A-type main-sequence star with a stellar classification of A0Vn,<ref name=abt/> a star that is currently fusing its core hydrogen. The 'n' suffix indicates "nebulous" absorption lines due to rapid rotation. It is around 181 million years old with a projected rotational velocity of 229 km/s.<ref name=David2015/> This spin rate is giving the star an oblate shape with an equatorial bulge that is an estimated 10% larger than the polar radius.<ref name=belle2012/> 16 Lyncis has 2.38<ref name=David2015/> times the mass of the Sun and is radiating 56<ref name=Anderson2012/> times the Sun's luminosity from its photosphere at an effective temperature of {{val|10395|fmt=commas|ul=K}}.<ref name=David2015/>
16 Lyncis is suspected of being slightly variable, but this has not been confirmed.<ref name="AAVSO"/> It was noted when 16 Lyncis was used as a comparison star for observing another variable, the peculiar HD 51418 (NY Aurigae).<ref name=gulliver/>
