| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 20003 b | 11.85 days | 0.0974 AU | at least 11.66 | 2019 | Radial Velocity | |
| HD 20003 c | 33.92 days | 0.1964 AU | at least 14.44 | 2019 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
