| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| iot Dra b | 510.9 days | 1.453 AU | at least 3,757 | 2002 | Radial Velocity | |
| iot Dra c | 68.45 years | 19.4 AU | at least 4,958 | 2021 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
