| Kepler-139 c | 157.1 days | 0.586 AU | 3.38 | 2014 | Transit | |
| Kepler-139 f | 355 days | 36 | 2025 | Transit Timing Variations | ||
| Kepler-139 e | 5.606 years | 3.236 AU | at least 426.1 | 2023 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
