| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 43197 b | 308.9 days | 0.882 AU | at least 175.8 | 2010 | Radial Velocity | |
| HD 43197 c | 25.45 years | 8.54 AU | 2,501 | 2022 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
