| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 187123 b | 3.097 days | 0.0426 AU | at least 166.2 | 1998 | Radial Velocity | |
| HD 187123 c | 10.43 years | 4.89 AU | at least 632.5 | 2008 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
