16 Camelopardalis is a single[10] star in the northern circumpolar constellation Camelopardalis,[9] located 348 light years away from the Sun as determined from parallax measurements.[1] It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 5.28.[2] This object is moving further from the Earth with a heliocentric radial velocity of around 12 km/s.[5]
This is an A-type main-sequence star with a stellar classification of A0 Vn,[4] where the 'n' notation indicates "nebulous" lines due to rapid rotation. In the past it was misidentified as a Lambda Boötis star.[11] It is around 400[7] million years old and is spinning with a projected rotational velocity of 217 km/s.[8] The star has 2.8[3] times the mass of the Sun and 3.3[7] times the Sun's radius. It is radiating 97[3] times the Sun's luminosity from its photosphere at an effective temperature of 9,748 K.[3]
An infrared excess indicates it has a dusty debris disk with a mean temperature of 120 K orbiting at a distance of 52 AU from the star. This disk has a combined mass equal to 2.1% the mass of the Earth.[7]
