- Apollo 17 rock 76535 may have been lifted to the surface by Serenitatis Basin impact about 4.25 billion years ago.
- This occurred 300 million years earlier than thought, and the rock formed nearly 50 kilometers deep.
- Led by Evan Bjonnes, the study uses computer simulations to support the surface-uplift scenario and notes the rock shows no signs of violent impacts.
