Explaining Planet Ejection in Planetary Forming Systems

Click For Summary
SUMMARY

High-mass planets can eject smaller planets during the formation of planetary systems due to gravitational interactions. When a smaller planet approaches a massive planet, gravitational attraction initially pulls it in; however, if the smaller planet does not collide and instead gains a new trajectory, it can escape the gravitational influence of the larger planet. This phenomenon is crucial in understanding the dynamics of planetary formation and migration.

PREREQUISITES
  • Understanding of gravitational interactions in astrophysics

It is said that high massive planets can eject small planets in planetary forming systems. I don't understand that since gravitation is supposed to attrack things. Do you know of any article that expains that kind of phenomenum?
 
Astronomy news on Phys.org
It attracts it, then the smaller planet, not having collided escapes with the same speed relative to the planet, but a new direction which puts it on an escape trajectory. See the explanations in the thread:

I'll check it out. Thanks.
