| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 177830 c | 110.9 days | 0.5137 AU | at least 47.67 | 2010 | Radial Velocity | |
| HD 177830 b | 410.1 days | 1.14 AU | at least 537.1 | 1999 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
