HD 20794 is 19.6 light-years from the Sun. The NASA Exoplanet Archive lists 4 planets around this G6 V star; the first was found in 2011 by radial velocity (La Silla Observatory).
Fly there in 3DHD 20794 b goes round its star every 18.3 days, 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.
