HD 168443 is 129 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G5 star; the first was found in 1998 by radial velocity (W. M. Keck Observatory).
Fly there in 3DHD 168443 b goes round its star every 58.1 days, 1.5 times as often as Mercury goes round the Sun.

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.
