GJ 649 is 33.9 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M1.0 star; the first was found in 2009 by radial velocity (W. M. Keck Observatory).
Fly there in 3DGJ 649 b takes 600.1 days 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.
