Iota Cephei (ι Cephei, ι Cep) is a Class K0, third-magnitude star in the constellation Cepheus. Iota Cephei is an orange giant star about 115 light-years from Earth. This star has 10.05 ± 0.18 times the Sun's radius and about 1.8–2.2 times the mass of the Sun. It is emitting 49.6 ± 2.5 times as much luminosity as the Sun, which is being radiated from its outer atmosphere at an effective temperature of 4,831 ± 74 K. Due to precession of the equinoxes, it will become the north pole star some time around 5200 CE.
