Star in the constellation Fornax
For other stars with this Bayer designation , see ι Fornacis .
Iota Fornacis is the Bayer designation for a star in the southern constellation of Fornax . It is faintly visible to the naked eye on a dark night, having an apparent visual magnitude of 5.83. The distance to this star, based upon an annual parallax shift of 29.46 mas , is around 111 light-years . It is a member of the thin disk population of the Milky Way galaxy .
This is an F-type main-sequence star with a stellar classification of F6 V Fe-0.7 CH-0.4. The suffix notation indicates that absorption lines of iron and the carbon–hydrogen G-band are abnormally weak. It has an estimated 1.42 times the mass of the Sun and 1.4 times the Sun's radius . The star is around 3.67 billion years old, and is spinning with a leisurely projected rotational velocity of 4.7 km/s.
Iota Fornacis has a common proper motion companion, a magnitude 13.74 star at a position angle of 81.80 arcseconds along a position angle of 6°. This object has about 35% of the Sun's mass.
