Since 90% of our training data is from the Primary Mission, we also test our ability to generalize on held-out 1st Extended Mission data.

The host star is at a distance of ~8. 1 parsecs, has a J-band magnitude of ~7. 2, and is observable from both hemispheres of Earth.

The combination of radius and mass measurements suggests that the innermost planet has a rocky composition similar to that of Earth, while the outer two planets have lower densities.

Mass-Radius Relationships for Solid Exoplanets

We find that the mass-radius relationships for cold terrestrial-mass planets of all compositions we considered follow a generic functional form that is not a simple power law: $\log_{10} R_s = k_1 + 1/3 \log_{10}(M_s) - k_2 M_s^{k_3}$ for up to $M_p \approx 20 M_{\oplus}$, where $M_s$ and $R_s$ are scaled mass and radius values.
