HD 219828 is 238 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G0 IV star; the first was found in 2007 by radial velocity (La Silla Observatory).
Fly there in 3DHD 219828 b goes round its star every 3.83 days, 23 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.
