The size–density relationship of TNOs. Sizes/densities updated here are shown by stars. For Varda, we use previous size/density measurements (W. M. Grundy et al. 2015) along with our new system mass. Other densities are from B. Proudfoot et al. (2025), F. L. Rommel et al. (2025), W. M. Grundy et al. (2019), E. Fernández-Valenzuela et al. (2025), and references therein. Unlabeled data points from lower left to upper right are Typhon, Teharonhiawako, Altjira, Ceto, Sila, Lempo, (612239), and (26308).
