I think I remember a talk where a professor said that Vesta is a particularly important asteroid because its gravity is strong enough to perturb other asteroids.
In spite of Vesta's size, this effect might be so strong that some smaller asteroids might be kicked out of their orbits - making their way to Jupiter, or to the inner solar system.
Can Vesta dominate the orbits of other asteroids?
All related to the one question, there are particular points I'm interested in:
- if so, how often, presumably?
- is there a preferred direction (inwards / outwards)?
- has the perturbation rate been constant over geologic timescales?
- do the "victims" stay in the plane of the ecliptic?
- did someone model such processes?
I currently think the whole process is chaotic - essentially unpredictable.
