Kepler-108 is 1,105 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,854 K star; the first was found in 2014 by transit (Kepler).
Fly there in 3DKepler-108 b goes round its star every 49.2 days, 1.8 times as often as Mercury goes round the Sun.
Kepler-108 is one of 2 stars in its system. The position of the other star is not catalogued, so only Kepler-108 and its planets are drawn.

|---|---|---|---|---|---|
| Kepler-108 b | 49.2 days | 0.292 AU | 8.65 R⊕ | 56 M⊕ estimated | Transit, 2014 |
| Kepler-108 c | 190.3 days | 0.721 AU | 8.18 R⊕ | 50.9 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 5,854 K, 5.1 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 2.14 to 3.76 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.
