HD 164604 is 128 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this K3.5 V star; the first was found in 2009 by radial velocity (Las Campanas Observatory).
Fly there in 3DHD 164604 c takes 14.7 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.
