Kepler-732 is 570 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 3,631 K star; the first was found in 2016 by transit (Kepler).
Fly there in 3DKepler-732 c goes round its star every 21.4 hours, 99 times as often as Mercury goes round the Sun.

|---|---|---|---|---|---|
| Kepler-732 c | 21.4 hours | 0.0143 AU | 1.27 R⊕ | 2.15 M⊕ estimated | Transit, 2016 |

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 3,631 K, 0.042 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.21 to 0.41 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.
