| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| GJ 180 b | 17.13 days | 0.092 AU | at least 6.49 | 2014 | Radial Velocity | |
| GJ 180 c | 24.33 days | 0.129 AU | at least 6.4 | 2014 | Radial Velocity | |
| GJ 180 d | 106.3 days | 0.309 AU | at least 7.56 | 2020 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
