HD 156279 is 118 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G6 star; the first was found in 2011 by radial velocity (Haute-Provence Observatory).
Fly there in 3DHD 156279 c takes 13.2 years to go round its star once.

|---|---|---|---|---|---|
| HD 156279 b | 133.4 days | 0.502 AU | 12.5 R⊕ estimated | 2997.8 M⊕ minimum | Radial Velocity, 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 5,453 K, 0.71 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.82 to 1.46 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.
