This star has a stellar classification of G8V,[3] indicating that it is a main-sequence star. Based upon stellar models, it has 82%[7] of the Sun's mass and 77%[2] of the radius. HD 14412 is spinning with a projected rotational velocity of 3.26 km/s[8] and is about 9.61 billion years old.[3] It is radiating 44%[2] of the luminosity of the Sun from its photosphere at an effective temperature of 5,482 K,[2] giving it the yellow-hued glow of a G-type star.[11]
HD 14412 has been examined for signs of an orbiting debris disk or a planetary companion, but as of 2012 none has been discovered.[12]
