gam Cep is 46.0 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K1 III-IV star; the first was found in 2003 by radial velocity (Multiple Observatories).
Fly there in 3Dgam Cep b takes 904.0 days to go round its star once.
gam Cep is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

gam Cep B has no spectral type listed of magnitude 7.3, with a computed orbit. In 2020 it was 1.8″ from gam Cep, at position angle 215° (Washington Double Star Catalog, 23393+7738 NHR 9 AB): 25.4 AU on the sky at this distance. The true distance can only be larger. Its colour is estimated from its brightness.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| gam Cep b | 904.0 days | 1.978 AU | 12.5 R⊕ estimated | 2987.6 M⊕ | Radial Velocity, 2003 |
Values are the NASA Exoplanet Archive’s composite parameters. A radius marked estimated comes from a mass–radius relation; a mass marked minimum is M sin i. Planet sizes and colours in the 3D view are renderings: none of these worlds has been photographed as more than a point of light.
