| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 12661 b | 262.7 days | 0.84 AU | at least 772.3 | 2000 | Radial Velocity | |
| HD 12661 c | 4.676 years | 2.814 AU | at least 575.9 | 2002 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
