Gravitational interactions between passing objects always has the potential to disturb the orbits of the two bodies involved, but I'm unaware of any research indicating that objects have been observed to have been perturbed OUTWARD from the Kuiper Belt to the far more distant (and hypothetical) Oort Cloud. It has probably happened, at least a FEW times. But the Kuiper Belt itself is so distant that our ability to detect comet-sized objects is quite limited. And aside from the philosophical argument of "Where do new comets come from, if not from the Oort cloud?", we have precisely ZERO actual evidence that the Oort Cloud exists as postulated.
There have been intermittent speculations that a massive but dark object, perhaps a planet or a brown dwarf star, might be in a highly elliptical orbit around the Sun. This object, occasionally named "Nemesis", might perturb distant Oort Cloud and Kuiper Belt objects out of their lazy orbits and drop them into the inner solar system as comets. The idea is that this might explain some strange periodicity of mass extinctions on Earth, that we might expect at any century a withering cosmic hailstorm of deadly proportion.
But the proposed math and timetables never seems to work out, and a massive enough object should have been discovered by now.
Short period comets are thought to originate in the Kuiper Belt, outside the orbit of Neptune.Long period comets originate in the Oort Cloud, which is far more distant, about half way to the nearest star!Comets, as with any astronomical body, can have its orbit perturbed (changed) by external gravitational forces. Long period comets can become short period and vice versa. The orbits can range from a few tens of years to many thousands, some can even escape altogether.
The Kuiper Belt is named after Gerard Kuiper; he was one of the only scientists who had theories about the Kuiper belt in the early fifties
The Kuiper Belt, a theorized area far beyond Neptune. There are actually two "shells" of debris around the Solar System. The Kuiper Belt is beyond Neptune, and the Oort Cloud is believed to be beyond that.
The most important part of a solar system is the sun at the center of the system. The sun is the foundation that keeps the solar system from flying off in different directions out into space. But more importantly Gravity is what keeps the planets in place due to the size of our sun.
Yes.
Pluto is at least 1 million years old according to scientists
the KUIPER BELT
Comets have two main sources, the Oort Cloud or the Kuiper Belt

Kuiper belt comets
The Kuiper belt is composed of asteroids and the Orrt cloud is composed of comets.
Comets are thought to have either originated from the Kuiper belt or the Oort cloud. The Oort cloud is much further out than the Kuiper belt, so comets with much longer periods are thought to originate from here, while shorter period comets are thought to mainly originate from the Kuiper belt. The Oort cloud extends as far out as 50,000 AU or nearly one light year from our sun - this is roughly where the boundary is for our solar systems gravitational influence. Passing stars and the gravitational effect of our galaxy are thought to dislodge objects from this hypothetical field of object, causing long term comets such as Halley's comet to enter into an eccentric orbit around our sun. The Kuiper belt, by contrast, extends from about 30 AU to 55AU. Generally speaking, the comets will be similar in composition, but those originating from the Oort cloud may have much longer periods and orbits.
Minor planets, comets, asteroids, and dust.

Short-period comets originate from the Kuiper Belt.
