| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 142 A d | 108.5 days | 0.474 AU | at least 82.64 | 2022 | Radial Velocity | |
| HD 142 b | 351.4 days | 1.039 AU | at least 397 | 2001 | Radial Velocity | |
| HD 142 c | 27.82 years | 9.811 AU | 3,465 | 2012 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
