HD 208741, also known as HR 8380, is a yellowish-white hued star located in the southern circumpolar constellation Octans. It has an apparent magnitude of 5.91, making it faintly visible to the naked eye. Parallax measurements place it at a distance of 211 light years, and it is currently receding with a heliocentric radial velocity of 8 km/s.
HD 208741 has a 10th magnitude K-type main-sequence companion separated by 34.8″. Together, they make up a wide binary system designated collectively as CPD−76°1542. Sir John Herschel, the discoverer of the pair, noted the primary to be a probable spectroscopic binary.
This object has a stellar classification of F3 III, indicating that it is a slightly evolved F-type star. Gaia Data Release 3 models it to be a dwarf that is 81.3% through its main sequence lifetime. At present it has 1.52 times the mass of the Sun and a slightly enlarged radius of 2.6 R☉ due to its evolved state. It radiates at 12.9 times the luminosity of the Sun from its photosphere at an effective temperature of 6,937 K. HD 208741 has a metallicity twice the Sun's, making it metal enriched. It is estimated to be 1.1 billion years old, and is spinning with a projected rotational velocity of 36 km/s.
