20 Cygni is a single, orange-hued star in the northern constellation of Cygnus. It is a faint star but is visible to the naked eye with an apparent visual magnitude of 5.03. The distance to 20 Cygni can be estimated from its annual parallax shift of 16 mas, which yields a range of 202 light years. It is moving closer to the Earth with a heliocentric radial velocity of −22 km/s.
