K2-350 is 1,596 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,789 K star; the first was found in 2016 by transit (K2).
Fly there in 3DK2-350 b goes round its star every 4.16 days, 21 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 | 5,789 K |
| Mass | 0.98 solar masses |
| Radius | 1.04 solar radii |
| Luminosity | 0.9733 times the Sun |
| Apparent magnitude | 13.449 |
| Distance from the Sun | 1596.1 light-years (489.4 parsecs) |
| Position (J2000) | RA 204.0355°, Dec -14.0093° |

| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| K2-350 b | 4.16 days | 0.0503 AU from Kepler’s law | 1.54 R⊕ | 2.99 M⊕ estimated | Transit, 2021 |
| K2-350 c | 20.0 days | 0.143 AU from Kepler’s law | 2.74 R⊕ | 7.95 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 5,789 K, 0.97 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.94 to 1.65 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.
