has abstract	HD 194953 (HR 7824) is a solitary star in the equatorial constellation Delphinus. It is faintly visible to the naked eye with an apparent magnitude of 6.19 and is located 414 light years away. However, it is approaching the Solar System with a heliocentric radial velocity of −28 km/s. HD 194953 has a stellar classification of G8 III/IV — a blended luminosity class of a subgiant and giant. It has 2.38 times the mass of the Sun and an enlarged radius of 10.2 R☉ at an age of 640 million years. It radiates at 54 times the luminosity of the Sun from its photosphere at an effective temperature of 5,101 K, giving a yellow hue. HD 194953 is slightly metal deficient with an iron abundance 78% that of the Sun and spins leisurely with a projected rotational velocity of about 2.4 km/s.
