Kepler-19 is 713 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this 5,541 K star; the first was found in 2011 by transit (Kepler).
Fly there in 3DKepler-19 b goes round its star every 9.29 days, 9 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.
| Surface temperature | 5,541 K |

| Constellation | Lyra |
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| Kepler-19 d | 63.0 days | 0.303 AU from Kepler’s law | 5.06 R⊕ estimated | 22.5 M⊕ | Radial Velocity, 2017 |
| Kepler-19 b | 9.29 days | 0.0846 AU | 2.209 R⊕ | 6.1 M⊕ | Transit, 2011 |

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 5,541 K, 0.69 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.80 to 1.42 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.
