Outrageous? No. There are comets not too mentione entire planets with no orbit just wondering around in space! At any time they could collide and
there you go. A change in direction. Hardly outrageous
Every body in our solar system IS in an orbit around a planet or the sun, no body can just be 'lingering' out there waiting to be 'nudged'. The
main asteroid belt for instance has remained stable since about a million years after the solar system accretion. There are also hundreds of asteroids
trapped in the Lagrangian points
of Jupiter, meaning they share the same orbit of Jupiter in
a gravitational lock directly opposite the sun and near 180º on each side in the orbital loop. Earth also has asteroids trapped in earth's
Lagrangian points, these bodies are also known as Trojan moons
. Saturn has 4 such moons
trapped in two of it's moons Lagrangian points.
Orbital dynamics is an interesting topic. Just be aware that when you are viewing an orbital trajectory in about 6 inches on your computer monitor
that the actual space involved is, well, astronomical. When you are viewing a diagram of the main asteroid belt it appears dense, but in fact the
amount of space we are talking about is huge, that it is far from 'crowded' out there. No deep space probe has ever collided with an asteroid that
traversed the belt, its harder to actually hit something out there than avoid hitting a body in space.
If nothing else you now may have just learned something you may not have already known.
