| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| GJ 273 c | 4.723 days | 0.03647 AU | at least 1.18 | 2017 | Radial Velocity | |
| GJ 273 b | 18.65 days | 0.0911 AU | at least 2.89 | 2017 | Radial Velocity |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
