| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 9446 b | 30.05 days | 0.189 AU | at least 222.5 | 2009 | Radial Velocity | |
| HD 9446 c | 192.9 days | 0.654 AU | at least 578.4 | 2009 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
