| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| Barnard d | 2.34 days | 0.0188 AU | at least 0.263 | 2025 | Radial Velocity | |
| Barnard b | 3.154 days | 0.0229 AU | at least 0.299 | 2024 | Radial Velocity | |
| Barnard c | 4.124 days | 0.0274 AU | at least 0.335 | 2025 | Radial Velocity | |
| Barnard e | 6.739 days | 0.0381 AU | at least 0.193 | 2025 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
