| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| rho CrB e | 12.9 days | 0.1061 AU | at least 3.71 | 2023 | Radial Velocity | |
| rho CrB b (disputed) | 39.85 days | 0.2245 AU | at least 348 | 1997 | Radial Velocity | |
| rho CrB c | 102 days | 0.4206 AU | at least 27.44 | 2016 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
