HD 12661 is 123 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this K0 star; the first was found in 2000 by radial velocity (Multiple Observatories).
Fly there in 3DHD 12661 c takes 4.7 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.
