Gl 686 is 26.6 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M1.0 V star; the first was found in 2018 by radial velocity (Roque de los Muchachos Observatory).
Fly there in 3DGl 686 b goes round its star every 15.5 days, 6 times as often as Mercury goes round the Sun.

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.
