| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HIP 111909 b | 487.1 days | 1.32 AU | at least 384.6 | 2025 | Radial Velocity | |
| HIP 111909 c | 2.447 years | 1.97 AU | at least 257.4 | 2025 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
