Expectations for Crater Size and Photometric Evolution from the Deep Impact Collision, the DI impact could create a crater 70m to 140m in diameter, depending on the scaling relation applied. Smaller than expected craters can be attributed either to the effect of strength limiting crater growth or to collapse of an unstable (deep) transient crater as a result of very high porosity and作者: 輕觸 時(shí)間: 2025-3-23 09:15 作者: flaunt 時(shí)間: 2025-3-23 12:33
