Kepler-188 is 3,159 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 6,021 K star; the first was found in 2014 by transit (Kepler).
Fly there in 3DKepler-188 b goes round its star every 2.06 days, 43 times as often as Mercury goes round the Sun.

|---|---|---|---|---|---|
| Kepler-188 b | 2.06 days | 0.0320 AU | 1.68 R⊕ | 3.46 M⊕ estimated | Transit, 2014 |

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 6,021 K, 1.1 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.97 to 1.71 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.
