Upper panel summarizes the light-curve studies for the CC population, and the lower one is for the other TNOs. The bubble size indicates the size of the objects (i.e., large bubbles for large objects). The largest visible bubble is for Makemake (H = −0.3 mag, periodicity of 7.65 hr). The same bubble scaling has been used for both plots, allowing a direct comparison between theses two populations. Because of their very long rotational periods (out of the plot’s scale), Sila–Nunam and Pluto-Charon are not plotted.
