I mean if every variable aligns with any possible edge case that can bleed off velocity including three body interactions with the moon. Is there ever a situation where some substantial (car++) or enormous (skyscraper+++) size rock lands on the surface without explosive energy? Align stars, consult math mediums, play some ZZ Top, piss off Bary the narcissist, or conjure a primordial black hole, just land me a big rock in my yard Science Santa. I want an m-type for Maymass, but any type will do if you can land it.
No, it’s not possible to soft-land a large falling object, even with extraordinary luck.
Our intuition serves us well in everyday situations. I think you’ll agree that, if you have a big rock 100 meters in the air, it’s going to hit the ground hard no matter how you drop or throw it. The bigger the rock, the more we can ignore things like air friction.
The same situation applies to objects in space. If it hits the Earth, it’s been falling the whole way from space. The minimum impact velocity is equal to the “height” of Earth’s gravity well, about 11.2 km/s.
