ELI5: What would happen to Earth if a larger planetoid passed by Earth at roughly the distance of the moon?

Bonus question: What would have to happen for said Planetoid to drift through space without directly physically affecting planet Earth or any other celestial body within the solar system?

Massive tidal waves all over the Earth. Something larger than the earth would have more gravitational pull on us causing our normal predictable tides to be catastrophic.

A chain reaction of weather conditions stemming from that would also cause massive damage to the world as we know it.
