Detailed View of Charon, Moon of Pluto
الشرح: Charon is the largest natural moon of the dwarf planet Pluto. This detailed image was taken by NASA’s New Horizons spacecraft in 2015 during its historic mission through the outer Solar System. Charon’s surface shows a fascinating mix of light and dark regions, including vast canyons, broad plains, and impact crater. With a diameter of about 1,200 kilometers, Charon is more than half the diameter of Pluto, making it unusually large compared to its parent body. Charon's mass is roughly 12% of that of Pluto.
Because Pluto and Charon are so close in mass, the center of mass of the system (the point both Pluto and Charon orbit) is not within Pluto but between Pluto and Charon. This is in contrast to systems like the Earth and its Moon where the center of mass lies within the larger body, the Earth in this case. Scientists think the Pluto-Charon system may have formed by a collision of two objects that then separated and began to orbit each other. By studying Charon and the smaller moons that circle Pluto, astronomers gain insight into how moons form and how distant icy bodies evolve over billions of years.
