| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 4203 b | 431.9 days | 1.17 AU | at least 708.8 | 2001 | Radial Velocity | |
| HD 4203 c | 18.34 years | 6.95 AU | at least 689.7 | 2014 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
