Iota2 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. [2] The distance to this star, based upon an annual parallax shift of 29.46 mas, is around 111 light-years. [1] It is a member of the thin disk population of the Milky Way galaxy. [9]
This is an F-type main-sequence star with a stellar classification of F6 V Fe-0.7 CH-0.4. [4] The suffix notation indicates that absorption lines of iron and the carbon–hydrogen G-band are abnormally weak. [11] It has an estimated 1.42 [7] times the mass of the Sun and 1.4 [8] times the Sun's radius. The star is around 3.67 billion years old, [9] and is spinning with a leisurely projected rotational velocity of 4.7 km/s. [6]
Iota2 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°. [3] This object has about 35% of the Sun's mass. [7]
