Ah. good questions! They informed me about the mechanisms: an unstable orbit from outside energy.berkeman said:What do you mean by the term "eject"? What was the previous orbit of the object? Where did the object come from? Unless it was already in an unstable orbit due to initial conditions, where did the extra energy come from to disturb the stable orbit and cause it to become unstable? Links?
Yes, Jupiter's massive gravitational pull can potentially eject a pebble in orbit around it if the pebble's velocity exceeds the escape velocity of Jupiter.
Yes, even a smaller mass like a pebble can be ejected by Jupiter's gravitational force if it reaches a velocity that surpasses Jupiter's escape velocity.
The main factors that determine if Jupiter can gravitationally eject an object in orbit include the object's mass, velocity, and distance from Jupiter, as well as Jupiter's own mass and escape velocity.
While it is not a common occurrence, Jupiter can and does gravitationally eject objects in orbit, especially smaller masses like pebbles that have enough velocity to escape Jupiter's gravitational pull.
Objects that are gravitationally ejected by Jupiter typically continue on a trajectory away from the planet, either entering into a new orbit around the Sun or being ejected out of the solar system altogether, depending on their velocity and direction.
