HD 14412 (22 G. Fornacis) is the Henry Draper catalogue designation for an ordinary star in the southern constellation Fornax. It has an apparent visual magnitude of 6.33,[2] which, according to the Bortle scale, can be dimly seen with the naked eye from rural locations. Based upon an annual parallax shift of 0.078.93 arc seconds as measured by the Hipparcos satellite, this system is 41.3 light-years (12.67 parsecs) from Earth.
This star has a stellar classification of G8 V,[2] indicating that it is a main sequence star. Based upon models, it has 82% of the Sun's mass and 77% of the radius.[5] HD 14412 is spinning with a projected rotational velocity of 3.26 km/s[6] and is about 9.61 billion years old.[2] The stellar atmosphere has an effective temperature of 5,359 K,[2] giving it the yellow-hued glow of a G-type star.[8]
HD 14412 has been examined for signs of an orbiting debris disk or a planetary companion, but as of 2012 none has been discovered.[9]
