| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HAT-P-11 b | 4.888 days | 0.05258 AU | at least 23.52 | 2010 | Transit | |
| HAT-P-11 c | 9.202 years | 4.1 AU | 851.8 | 2018 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
