7 CMa is 64.6 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this K1III(+M) star; the first was found in 2011 by radial velocity (Anglo-Australian Telescope).
Fly there in 3D7 CMa c takes 996.0 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.
