Distribution of known transiting planets in the planet radius–orbital period plane, showing the boundaries of the “hot Neptune desert” and “Neptunian ridge” (the overdensity of intermediate-sized planets between 3 and 6 days between the vertical dashed lines), as defined by A. Castro-González et al. (2024). TOI-2374b is part of the Neptunian ridge and is shown as the red star. Planets with no obliquity measurements are shown in gray, planets with low measured obliquities are shown in blue, while planets with misaligned orbits (λ more than 1σ greater than 15°) are shown in red. Square symbols denote planets with radii between 5.5 and 8.5 R_⊕, while triangles denote those with R_p between 4.0 and 5.5 R_⊕. Planet properties were drawn from the NASA Exoplanet Archive PSCompPars table (NASA Exoplanet Archive 2022) as of 2025 June 5, while obliquity measurements were compiled from S. H. Albrecht et al. (2022), E. Knudstrup et al. (2024), and the TEPCat catalog (J. Southworth 2011).
