All small (R_P ≤ 1.8 R_⊕), rocky planets from the Exoplanet Archive (J. L. Christiansen et al. 2025) with <30% fractional radius and mass uncertainties (gray points). Planets with masses and radii consistent with a rocky composition (pure iron to pure MgSiO₃ rock) are contained within the brown shaded region (L. Zeng et al. 2019). Our rocky planet sample with host star abundances from SDSS-V is shown in color, which corresponds to host star [Fe/H]. Planets hosted by FGK dwarfs are marked as circles, while planets hosted by M dwarfs are marked as triangles. The one planet not contained within the L. Zeng et al. (2019) region is TOI-561 b, the only high-confidence thick disk planet in our sample. We also label Kepler-10 b, another possible thick disk planet.
