Kepler-315 is 3,786 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,796 K star; the first was found in 2014 by transit (Kepler).
Fly there in 3DKepler-315 c takes 265.5 days to go round its star once.

|---|---|---|---|---|---|
| Kepler-315 b | 96.1 days | 0.402 AU | 3.77 R⊕ | 13.7 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 5,796 K, 1.0 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.95 to 1.68 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.
