I can’t offer you much hope for this world, but I can tell you of another world, Bennu, and its compulsion to throw rocks.
Back in January 2019, planetary scientists noticed particles catching the light as they flew away from this orbiting pile of rocks. In image after image, pebbles were seen hopping up and landing elsewhere or flying away altogether. These observed paths allowed some unexpected research to be completed! According to Steve Chelsey: The particles were an unexpected gift for gravity science at Bennu since they allowed us to see tiny variations in the asteroid’s gravity field that we would not have known about otherwise.
The source of these far-flung rocks remains a bit of a mystery. It looks like a combination of thermal fracturing and impacting meteors or one or the other of these effects may be providing the energy to launch pebbles into space. In the case of thermal fracturing, we’re looking at the constant heating and cooling of rocks causing them to actually break, and break with enough force to launch things. With meteorites, this is literally a case of space throwing rocks at Bennu, and those impacts causing Bennu to throw rocks back at space.
