Kepler-520 is 2,035 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 6,112 K star; the first was found in 2016 by transit (Kepler).
Fly there in 3DKepler-520 c goes round its star every 5.21 days, 17 times as often as Mercury goes round the Sun.

|---|---|---|---|---|---|
| Kepler-520 c | 5.21 days | 0.0604 AU | 1.07 R⊕ | 1.24 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 6,112 K, 3.2 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.68 to 2.93 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.
