27 Lyncis is a single[6] star in the northern constellation of Lynx. It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 4.78.[2] This object is located around 250 light years away from the Sun, as determine from parallax measurements.[1] It is moving further from the Sun with a heliocentric radial velocity of +11 km/s.[2]

This is an ordinary A-type main-sequence star with a stellar classification of A2 V,[3] which indicates it is generating energy through hydrogen fusion at its core. It is 157[4] million years old and is spinning with a projected rotational velocity of 183.[4] The star has 2.24[4] times the mass of the Sun and is radiating 65[2] times the Sun's luminosity from its photosphere at an effective temperature of 10,014 K.[4] X-ray emission is being detected near these coordinates, which may be coming from an undetected companion or a background source.[7]
