HD 141399 is 121 light-years from the Sun. The NASA Exoplanet Archive lists 4 planets around this K0 star; the first was found in 2014 by radial velocity (Multiple Observatories).
Fly there in 3DHD 141399 e takes 13.7 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.
For a star of 5,600 K, 1.6 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.21 to 2.15 AU. 1 of its 4 known planets orbits inside it. The zone says how much starlight arrives, not whether a planet has water or air. The edges follow Kopparapu et al. (2014), as the 3D view draws them.
