| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 5278 b | 14.34 days | 0.1202 AU | 2.45 | 7.8 | 2021 | Transit |
| HD 5278 c | 40.87 days | 0.2416 AU | at least 18.4 | 2021 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
