Exploring the Oort Cloud: How Long Do Comets Stay Near Planets?

The study explores how comets from the Oort Cloud interact with planets, using models to simulate their evolution under galactic tides, stellar encounters, and planetary forces. It finds that comets typically stay in the planetary region for about 100 million years before being ejected or transitioning into other populations like Centaurs. These findings reveal how dynamic forces shape the solar system's structure and history.
