Charon’s Mountains Reveal Moon Once Spun 10x Faster
Scientists analyzed data from NASA’s New Horizons mission to Pluto and found that Charon, Pluto’s largest moon, may have once rotated up to 10 times faster than it does now. The study suggests that Charon’s current surface features, including distinct geological differences between its hemispheres, could be the result of a slow-down in its rotation early in its history. This despinning likely occurred before any cryovolcanic activity and may have caused global contraction, offering insights into the moon’s early thermal and mechanical evolution. The findings help scientists better understand the formation and development of icy moons in the outer solar system.
Scientists found that Pluto's moon Charon may have once spun 10 times faster than it does now, based on analysis of its mountainous terrain and geological features.
This discovery helps scientists understand how Charon and other icy moons in the outer solar system formed and evolved over time.
The study offers a glimpse into the dynamic history of distant celestial bodies, advancing our knowledge of planetary science in a calm, methodical way.
