| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| GJ 3473 b | 1.198 days | 0.01589 AU | 1.264 | 1.86 | 2020 | Transit |
| GJ 3473 c | 15.51 days | 0.0876 AU | at least 7.41 | 2020 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
