| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| K2-105 c | 5.022 days | 0.0559 AU | at least 11.1 | 2026 | Radial Velocity | |
| K2-105 b | 8.267 days | 0.078 AU | 3.145 | 5 | 2017 | Transit |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
