RR Cae is 69.1 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M star; the first was found in 2012 by eclipse timing variations (Leoncito Astronomical Complex).
Fly there in 3DRR Cae b takes 11.9 years to go round its star once.
RR Cae is one of 2 stars in its system. The position of the other star is not catalogued, so only RR Cae 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.
