Chi2 Fornacis, Latinized as χ2 Fornacis, is a solitary star located in the southern constellation Fornax, the furnace. It is faintly visible to the naked eye as an orange-hued point of light with an apparent magnitude of 5.70. Gaia DR3 parallax measurements imply a distance of 476 light-years and it is currently receding with a heliocentric radial velocity of approximately 30 km/s.[6] At its current distance, Chi2 Fornacis' brightness is diminished by an interstellar extinction of 0.11 magnitudes[15] and it has an absolute magnitude of 0.00.[7]

Chi2 Fornacis is an old-disk star[11] and it has a stellar classification of K2 III.[3] The class indicates that it is an evolved K-type giant that has ceased hydrogen fusion at its core and left the main sequence. It has 118% the mass of the Sun[8] but it has expanded to 23.58 times the radius of the Sun.[9] It radiates 194 time the luminosity of the Sun[1] from its photosphere at an effective temperature of 4,477 K.[10] Chi2 Fornacis is slightly metal enriched with a near-solar iron abundance of [Fe/H] = +0.02.[11] It spins too slowly for its projected rotational velocity to be measured accurately, having a projected rotational velocity lower than 1.0 km/s.[12]

The star was observed to be variable in infrared light during a 1991 IRAS survey for galaxy clusters.[16] However, its variability in optical light is unknown. In addition, subsequent observations have not confirmed the variability in infrared and optical light.[17] The lenticular galaxy NGC 1380 lies 2 degrees north-northeast of Chi2 Fornacis.[18]
