27 Cygni is a subgiant star in the northern constellation of Cygnus. It is faintly visible to the naked eye with an apparent visual magnitude of 5.38. The distance to this system, as estimated from its annual parallax shift of 41.77 mas, is 78.1 light-years. At that distance, the visual magnitude is diminished by an extinction of 0.05 due to interstellar dust. It is moving closer to the Earth with a heliocentric radial velocity of −33 km/s, and has a relatively high proper motion, traversing the celestial sphere at the rate of 0.495″ per year.
