| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| GJ 357 b | 3.931 days | 0.036 AU | 1.2 | 2019 | Transit | |
| GJ 357 c | 9.125 days | 0.061 AU | at least 3.4 | 2019 | Radial Velocity | |
| GJ 357 d | 55.66 days | 0.204 AU | at least 6.1 | 2019 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
