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.
The trajectories of celestial bodies are time-reversible (neglecting things like atmospheric drag and tidal forces). So any encounter would be physically valid if you ran it in reverse—which means anything approaching or leaving the earth would need to be moving at escape velocity (25,000 mph) or faster.
No neglecting allowed, but cool trick. Break a contact binary at an ideal moment/composition/spin.
