Kepler-1647 is 3,955 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 6,210 K star; the first was found in 2016 by transit (Kepler).
Fly there in 3DKepler-1647 b takes 3.0 years to go round its star once.
Kepler-1647 is one of 2 stars in its system. The position of the other star is not catalogued, so only Kepler-1647 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 6,210 K, 4.4 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.94 to 3.39 AU. Its one known planet 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.
