| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 156668 b | 4.646 days | 0.05 AU | at least 4.15 | 2010 | Radial Velocity | |
| HD 156668 c | 2.221 years | 1.57 AU | at least 31.5 | 2021 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
