rdfs:comment	16 Cephei, som är stjärnans Flamsteed-beteckning, är en ensam stjärna i den mellersta delen av stjärnbilden Cepheus. Den har en skenbar magnitud på ca 5,04 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 27,4 mas, beräknas den befinna sig på ett avstånd på ca 119 ljusår (ca 37 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -21 km/s. Stjärnan har en relativt snabb egenrörelse och förflyttar sig över himlavalvet med en hastighet av 0,174 bågsekunder per år.

has abstract	16 Cephei is a single star located about 119 light years away from the Sun in the constellation of Cepheus. It is visible to the naked eye as a faint, yellow-white hued star with an apparent visual magnitude of 5.036. The star has a relatively high proper motion, traversing the celestial sphere at the rate of 0.174 arc seconds per annum. It is moving closer to the Earth with a heliocentric radial velocity of −21 km/s. This is an ordinary F-type main-sequence star, somewhat hotter than the sun, with a stellar classification of F5 V. It is around two billion years old with a projected rotational velocity of 26.4 km/s. The star has 1.38 times the mass of the Sun and 2.77 times the Sun's radius. It is radiating 11 times the luminosity of the Sun from its photosphere at an effective temperature of 6,238 K. The star is a source of X-ray emission. There are several 11th and 12th magnitude stars within a few arc-minutes of 16 Cephei, all of them distant background objects. Only one of these is listed in the Washington Double Star Catalog and Catalog of Components of Double and Multiple Stars as a companion. (en)
