GJ 849 is 28.7 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this M3.5 star; the first was found in 2006 by radial velocity (W. M. Keck Observatory).
Fly there in 3DGJ 849 c takes 16.4 years to go round its star once.

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.
