Kepler-879 is 2,618 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G star; the first was found in 2016 by transit (Kepler).
Fly there in 3DKepler-879 c goes round its star every 15.5 hours, 136 times as often as Mercury goes round the Sun.
Where the archive gives only a period or only an orbit size, the other is worked out from Kepler’s third law with the star’s mass.

| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| Kepler-879 c | 15.5 hours | 0.0147 AU from Kepler’s law | 0.4 R⊕ | 0.0364 M⊕ estimated | Transit, 2024 |
| Kepler-879 b | 33.4 days | 0.201 AU | 2.57 R⊕ | 7.13 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 5,792 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 0.99 to 1.74 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.
