Eta2 Fornacis (η2 Fornacis) is an orange giant in the constellation of Fornax. The star has a spectral type of K0III and an apparent magnitude of 6.02. The star is visually close to, but unrelated with the similar stars η1 Fornacis and η3 Fornacis. [4] The star is located at approximately 425 light years away, and forms a visual binary system with a 10th magnitude companion. [6]
