HD 169405 (HR 6894), is a suspected binary star[7] system in the southern constellation Telescopium, about a degree to the north of Zeta Telescopii.[8] It has an apparent magnitude of 5.44,[2] making it faintly visible to the naked eye under ideal conditions. HD 169405 is located at a distance of 267 light years[1] and is drifting away with a heliocentric radial velocity of 3.8 km/s.[2]

The visible component has a spectral classification K0.5III[3] which indicates that it is an evolved star between a K0 and K1 giant. It has expanded to ten times the Sun's radius, shines at 35 solar luminosities, and has an effective temperature of 5,062 K.[4] This temperature gives it the yellowish-orange glow of a K-type star, and it spins slowly with a projected rotational velocity of 2.7 km/s.[5]
