TL;DR: An impact experiment on Ryugu is described using Hayabusa2’s Small Carry-on Impactor, which produced an artificial crater with a diameter >10 meters, which has a semicircular shape, an elevated rim, and a central pit, and implications for Ryugu's surface age are discussed.

TL;DR: The authors conclude that the asteroid experienced a prior period of strong solar heating caused by changes in its orbit, and suggest that Ryugu previously experienced an orbital excursion near the Sun.
