Montagne asimmetriche nella regione equatoriale di Oz Terra, lunghe oltre 200 chilometri, e faglie orientate lungo precise direttrici polari. È la firma geologica che il rallentamento della rotazione impresso dalle forze mareali (un processo noto come despinning) ha inciso sulla crosta ghiacciata di Caronte, la luna piΓΉ grande di Plutone. Il geologo planetario Hanzhang Chen, […]
