Explaining Planet Ejection in Planetary Forming Systems

In summary, planet ejection is a process in which a planet is removed from its original orbit in a planetary forming system due to interactions with other planets or celestial bodies, or gravitational forces from the parent star. It is a relatively rare occurrence, with only about 1% of planets experiencing ejection. Several factors can contribute to planet ejection, including gravitational interactions, binary star systems, and the structure of the protoplanetary disk. However, planet ejection can also result in the formation of new planets in different orbits, making it a crucial process in understanding the diversity of planetary systems in our universe.

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?

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.
 

1. What is Planet Ejection in Planetary Forming Systems?

Planet ejection is a process in which a planet is removed from its original orbit in a planetary forming system. This can happen due to interactions with other planets or celestial bodies, or due to gravitational forces from the parent star.

2. How common is Planet Ejection in Planetary Forming Systems?

Planet ejection is a relatively rare occurrence in planetary forming systems. It is estimated that only about 1% of planets in forming systems experience ejection.

3. What factors contribute to Planet Ejection in Planetary Forming Systems?

There are several factors that can contribute to planet ejection in planetary forming systems. These include gravitational interactions with other planets or celestial bodies, the presence of a close binary star system, and the protoplanetary disk's density and structure.

4. Can Planet Ejection in Planetary Forming Systems result in the formation of new planets?

Yes, planet ejection can lead to the formation of new planets in a planetary forming system. When a planet is ejected, it can carry with it material from the protoplanetary disk, which can then coalesce and form new planets in different orbits.

5. How does the study of Planet Ejection in Planetary Forming Systems contribute to our understanding of planet formation?

Studying planet ejection in planetary forming systems can provide insights into the complex processes involved in the formation of planets. It can also help us understand the factors that can disrupt or alter the formation of planets, leading to a better understanding of the diversity of planetary systems in our universe.
