| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 203387 b | 512.5 days | 1.771 AU | at least 1,106 | 2022 | Radial Velocity | |
| HD 203387 c | 6.793 years | 5.067 AU | 2,379 | 2022 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
