HD 12467 is a single[11] star in the northern circumpolar constellation of Cepheus. It has a white hue and is barely visible to the naked eye with an apparent visual magnitude of 6.05.[2] The distance to this object is 231 light years based on parallax,[1] but it is drifting closer with a heliocentric radial velocity of −9 km/s.[5]

This object is an ordinary A-type main-sequence star with a stellar classification of A1.5V,[3] which indicates it is generating energy through core hydrogen fusion. It is 254[7] million years old with a relatively high projected rotational velocity of 130 km/s.[9] The star has 1.8[7] times the mass of the Sun and 1.9[8] times the Sun's radius. It is radiating 16[6] times the luminosity of the Sun from its photosphere at an effective temperature of 8,528 K.[7]

The star displays an infrared excess with a signature that suggests it has two debris disks. The inner disk is orbiting 7.4 AU from the host star with a mean temperature of 200 K, while the outer disk is 50 K at a separation of 119 AU.[8]
