HD 33142 is 396 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this K0 III star; the first was found in 2011 by radial velocity (W. M. Keck Observatory).
Fly there in 3DHD 33142 c takes 810.2 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.
