| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 219828 b | 3.835 days | 0.049 AU | at least 19.07 | 2007 | Radial Velocity | |
| HD 219828 c | 13.11 years | 5.657 AU | 5,102 | 2016 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
