| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 20794 b | 18.31 days | 0.1257 AU | at least 2.15 | 2011 | Radial Velocity | |
| HD 20794 d | 89.68 days | 0.3625 AU | at least 2.98 | 2011 | Radial Velocity | |
| HD 20794 e (disputed) | 147 days | 0.509 AU | at least 4.77 | 2017 | Radial Velocity | |
| HD 20794 f | 647.6 days | 1.354 AU | at least 5.82 | 2025 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
