| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 216520 b | 35.45 days | 0.198 AU | at least 10.26 | 2020 | Radial Velocity | |
| HD 216520 c | 154.4 days | 0.528 AU | at least 9.44 | 2020 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
