| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 133131 A b | 649 days | 1.44 AU | at least 451.3 | 2016 | Radial Velocity | |
| HD 133131 A c | 9.769 years | 4.49 AU | at least 133.5 | 2016 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
