HD 65216 is 115 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G5 V star; the first was found in 2003 by radial velocity (La Silla Observatory).
Fly there in 3DHD 65216 c takes 14.7 years to go round its star once.
HD 65216 is one of 3 stars in its system: HD 65216 B drawn from the Washington Double Star Catalog; the position of one more star is not catalogued, so it is not drawn.

HD 65216 B is a M7/8 star of magnitude 12.7, judged a true companion. In 2015 it was 7.2″ from HD 65216, at position angle 90° (Washington Double Star Catalog, 07537-6339 MUG 8 AB): 253 AU on the sky at this distance. The true distance can only be larger.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| HD 65216 b | 577.6 days | 1.301 AU | 13.6 R⊕ estimated | 411.59 M⊕ minimum | Radial Velocity, 2003 |

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.
