HD 177406, also known as HR 7223 or rarely "47 G. Telescopii", is a solitary star located in the southern constellation Telescopium. It is faintly visible to the naked eye as a white-hued point of light with an apparent magnitude of 5.95. Gaia DR3 parallax measurements imply a distance of 369 light years and it is currently approaching the Solar System with a heliocentric radial velocity of . At its current distance, HD 177406's brightness is diminished by 0.23 magnitudes due to interstellar dust and it has an absolute magnitude of +0.60.
HD 177406 has a stellar classification of A0 V, indicating that it is an ordinary A-type main-sequence star that is generating energy via hydrogen fusion at its core. It has 2.64 times the mass of the Sun and a radius 2.55 times that of the Sun. It radiates 62.4 times the luminosity of the Sun from its photosphere at an effective temperature of . It has a solar metallicity at [Fe/H] = +0.00 and it is estimated to be 286 million years old, having completed 58.66% of its main sequence lifetime.
