| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 154857 b | 408.6 days | 1.29 AU | at least 778.7 | 2004 | Radial Velocity | |
| HD 154857 c | 9.451 years | 5.36 AU | at least 820 | 2014 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
