| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 33142 d | 89.9 days | 0.452 AU | at least 63.57 | 2022 | Radial Velocity | |
| HD 33142 b | 330 days | 1.074 AU | at least 400.5 | 2011 | Radial Velocity | |
| HD 33142 c | 2.218 years | 1.955 AU | at least 282.9 | 2016 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
