| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| BD-210397 b | 5.177 years | 2.63 AU | at least 214 | 2023 | Radial Velocity | |
| BD-210397 c | 17.08 years | 5.9 AU | 1,526 | 2023 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
