On The Origin of Pluto , Charon , and the Pluto
Being small, binary, and in a highly unusual orbit, Pluto was long viewed as an enigma in the outer Solar System. Here we review the historical development of ideas concerning Pluto's origin and the origin of the Pluto-Charon Binary. We critically examine these theories in light of both recent advances about Pluto, and with regard to Pluto's broader context in the outer Solar System. Although P...
متن کاملA giant impact origin of Pluto-Charon.
Pluto and its moon, Charon, are the most prominent members of the Kuiper belt, and their existence holds clues to outer solar system formation processes. Here, hydrodynamic simulations are used to demonstrate that the formation of Pluto-Charon by means of a large collision is quite plausible. I show that such an impact probably produced an intact Charon, although it is possible that a disk of m...
متن کاملOn an impact origin of Pluto-Charon
Walnut Street, Suite 400, Boulder, CO 80302 [email protected], Earth Sciences Department, University of California; Santa Cruz, CA 95064. Introduction: The Pluto-Charon system shares key commonalities with the Earth-Moon system, e.g., its large satellite-to-planet mass ratio, high system angular momentum and a potentially reduced satellite density relative to that of the planet. In both ca...
متن کاملOrigin and Evolution of Water in the Moon's Interior
Nearly forty years after the return of the first lunar samples to Earth, improvements in laboratory detection limits made possible the first definitive discovery of magmatic water in lunar volcanic samples. The intervening decade has seen an exponential increase in the amount of data on the abundance of magmatic water, and its hydrogen isotope composition, in various rock types recovered from t...
متن کاملOrigin of the Pluto–Charon system: Constraints from the New Horizons flyby
New Horizon’s accurate determination of the sizes and densities of Pluto and Charon now permit precise internal models of both bodies to be constructed. Assuming differentiated rock-ice structures, we find that Pluto is close to 2/3 solar-composition anhydrous rock by mass and Charon 3/5 solar-composition anhydrous rock by mass. Pluto and Charon are closer to each other in density than to other...
