| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| K2-157 b | 0.3653 days | 0.00962 AU | 0.935 | 1.14 | 2018 | Transit |
| K2-157 c | 25.94 days | 0.165 AU | at least 30.8 | 2025 | Radial Velocity | |
| K2-157 d | 66.5 days | 0.309 AU | at least 23.3 | 2025 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
