Astronomers have identified enormous landslides on Pluto, with some so large they would be capable of burying entire cities on Earth. The finding adds another dramatic feature to the dwarf planet and points to a surprisingly active landscape shaped by ice, gravity and long-moving debris.
What stands out most is how far the material appears to have traveled. Researchers say the runout distances make Pluto’s landslides some of the most mobile seen anywhere in the solar system, suggesting that once the debris started moving, it was able to keep going far longer than similar collapses on many other worlds.
The leading explanation is tied to Pluto’s unusual surface conditions. Its low gravity would make it easier for falling material to continue downslope, while low-friction icy rubble could help the debris slide and spread over great distances instead of stopping quickly.
The discovery offers another clue to how Pluto’s surface evolves in extreme cold. Even from limited observations, the apparent scale and mobility of these icy landslides show that the distant world is far more complex than a frozen, inactive object at the edge of the solar system.
