| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 153557 b | 7.299 days | 0.068 AU | at least 20.34 | 2022 | Radial Velocity | |
| HD 153557 c | 15.27 days | 0.111 AU | at least 17.48 | 2022 | Radial Velocity | |
| HD 153557 d | 111.3 years | 21.45 AU | 8,726 | 2022 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
