How do planets clear out objects on the other side of their orbit?

NASA explains that for an object to be classified as a planet, it needs to have enough mass to gravitationally clear out other objects of similar size from its orbital path. This involves not just direct gravitational influence but also the phenomenon of orbital resonances, where planets can exert gravitational pulls that effectively nudge other objects out of the way, even from the opposite side of their orbit. This dynamic process is crucial for maintaining the planet's status and helps astronomers understand the stability and evolution of planetary systems. Understanding how planets clear their orbits provides insight into the broader dynamics of our solar system and beyond.
