| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HD 147873 b | 116.6 days | 0.522 AU | at least 1,634 | 2016 | Radial Velocity | |
| HD 147873 c | 491.5 days | 1.36 AU | at least 731 | 2016 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
