HD 142 is 85.4 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this F7V star; the first was found in 2001 by radial velocity (Anglo-Australian Telescope).
Fly there in 3DHD 142 c takes 27.8 years to go round its star once.
HD 142 is one of 2 stars in its system. The position of the other star is not catalogued, so only HD 142 and its planets are drawn.

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.
