characteristics
mass, radius , temperature

kepler-16b gas giant, exoplanet near same mass , radius planets jupiter , saturn. has temperature of 188 k (−85 °c; −121 °f). planet has radius of 0.77 rj, larger saturn, , has no solid surface.

host stars

the planet orbits in circumbinary orbit around (k-type) , (m-type) binary star system. stars orbit each other every 41 days. stars have masses of 0.68 m☉ , 0.20 m☉ , radii of 0.64 r☉ , 0.22 r☉, respectively. have surface temperatures of 4450 k , 3311 k. based on stellar characteristics , orbital dynamics, estimated age of 2 billion years system possible. in comparison, sun 4.6 billion years old , has surface temperature of 5778 k.

the apparent magnitude of system, or how bright appears earth s perspective, unknown.

orbit

kepler-16b orbits around parent stars 14% , 0.5% of sun s luminosity, respectively, every 228 days @ distance of 0.704 au stars (nearly same distance venus orbits sun, 0.71 au).
