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.

|---|---|---|---|---|---|
| Kepler-879 c | 15.5 hours | 0.0147 AU from Kepler’s law | 0.4 R⊕ | 0.0364 M⊕ estimated | Transit, 2024 |

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.
