GJ 86 is 35.2 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K1V star; the first was found in 1999 by radial velocity (La Silla Observatory).
Fly there in 3DGJ 86 b goes round its star every 15.8 days, 6 times as often as Mercury goes round the Sun.
GJ 86 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

GJ 86 B is a DQ6 star of magnitude 13.2, with a computed orbit. In 2016 it was 2.6″ from GJ 86, at position angle 82° (Washington Double Star Catalog, 02104-5049 ESG 1): 28.0 AU on the sky at this distance. The true distance can only be larger.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| GJ 86 b | 15.8 days | 0.110 AU | 12.9 R⊕ estimated | 1404.8 M⊕ minimum | Radial Velocity, 1999 |
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 5,182 K, 0.41 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.63 to 1.13 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.
