HU Aqr is 627 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,952 K star; the first was found in 2011 by eclipse timing variations (Yunnan Astronomical Observatory).
Fly there in 3DHU Aqr AB c takes 12.0 years to go round its star once.
HU Aqr is one of 2 stars in its system. The position of the other star is not catalogued, so only HU Aqr 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.
