HD 190360 is 52.2 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this G7 IV-V star; the first was found in 2003 by radial velocity (Haute-Provence Observatory).
Fly there in 3DHD 190360 c goes round its star every 17.1 days, 5 times as often as Mercury goes round the Sun.
HD 190360 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

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.
