| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| 47 UMa b | 2.951 years | 2.1 AU | at least 804.1 | 1996 | Radial Velocity | |
| 47 UMa c | 6.546 years | 3.6 AU | at least 171.6 | 2001 | Radial Velocity | |
| 47 UMa d | 38.34 years | 11.6 AU | at least 521.2 | 2009 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
