HD 43197 is 204 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G8 V star; the first was found in 2010 by radial velocity (La Silla Observatory).
Fly there in 3DHD 43197 c takes 25.5 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.
