Kepler-16 is 245 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 4,450 K star; the first was found in 2011 by transit (Kepler).
Fly there in 3DKepler-16 b takes 228.8 days to go round its star once.
Kepler-16 is one of 2 stars in its system. The position of the other star is not catalogued, so only Kepler-16 and its planets are drawn.

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.
For a star of 4,450 K, 0.13 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.36 to 0.66 AU. None of its known planets orbits inside it. The zone says how much starlight arrives, not whether a planet has water or air. The edges follow Kopparapu et al. (2014), as the 3D view draws them.
