Kepler-68 is 470 light-years from the Sun. The NASA Exoplanet Archive lists 4 planets around this 5,847 K star; the first was found in 2013 by transit (Kepler).
Fly there in 3DKepler-68 b goes round its star every 5.40 days, 16 times as often as Mercury goes round the Sun.
Kepler-68 is one of 2 stars in its system. The position of the other star is not catalogued, so only Kepler-68 and its planets are drawn.

| Kepler-68 d | 632.6 days | 1.469 AU | 13.9 R⊕ estimated | 267 M⊕ | Radial Velocity, 2013 |

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 5,847 K, 1.7 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.23 to 2.17 AU. 1 of its 4 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.
