Scientists believe that comets primarily originate from two regions in the solar system: the Kuiper Belt and the Oort Cloud. The Kuiper Belt, located beyond Neptune's orbit, contains short-period comets, while the Oort Cloud, a distant spherical shell surrounding the solar system, is thought to be the source of long-period comets. These regions are rich in icy bodies that, when disturbed, can be sent into the inner solar system, creating the spectacular tails associated with comets.

The Kuiper Belt, located beyond the orbit of Neptune, contains icy bodies that can become comets when they are perturbed. The Oort Cloud, a distant and spherical shell surrounding the solar system, is thought to be the source of long-period comets that can travel from far beyond the planets.
Asteroids and comets are two examples of objects in the solar system besides moons and planets. Asteroids are rocky objects that orbit the Sun, mostly found in the asteroid belt between Mars and Jupiter. Comets are icy bodies that also orbit the Sun, with tails that form when they come close to the Sun.
In prehistoric times large objects have caused big craters. Whether before impact these would have appeared like comets is a matter for debate. A comet is a celestial body. Anything that enters the earths atmosphere and/or strikes the earth is deemed a meteorite
All orbits are ellipses; this is true for both planets and for comets. Cometary orbits are somewhat extreme ellipses, where the difference between the perihelion (closest to the Sun) is very different from the aphelion (farthest from the Sun) distance. This difference is called "eccentricity". Planets have relatively low eccentricity; for Earth, for example, the eccentricity is only 3%. Some comets don't have an "orbit" at all. An "orbit" implies that the comet will eventually come back. But some comets are "hyperbolic"; their paths aren't an ellipse, but a hyperbola. A hyperbolic comet is a one-time visitor to the solar system; it has fallen in from interstellar space, and will be going back out to interstellar space.
Comets have elliptical orbits as do planets, in general a comets orbit is more elliptical than a planets orbit. In some cases far more, insomuch as they are temporary visitors to our solar system. --- Comets are small bodies of rock and ice which are in a highly eccentric orbit around the sun. They spend most of their time slowly orbiting the sun, far out beyond the outer planets. Their orbit eventually brings them closer to the sun where they can then be seen more easily as the sun heats the surface and causes gas and dust to come away from the comet. Planets have much more regular orbits, their distance from the sun varies too, but to a much lesser degree. Planets orbits dont cross each others, and they are all on a similar plane. comets orbits are not always on the planetary plane and will cross the orbits of many planets throughout their eccentric orbit.
Asteroids comets and meteoroids all are masses of land sometimes inflamed and usually come from parts of planets hurtling through space.
As far as we know, no rogue planet has ever come near Earth. Comets and asteroids have come near Earth, but not actual planets.
They come from the outer reaches of space.

The planets in the solar system are in well-spaced out, stable, roughly circular orbits - they don't come close enough to collide with each other. Asteroids and comets, however, are on more elliptical, unstable orbits that often cross the orbits of the planets, and sometimes planets collide with asteroids and comets.
Mostly comets follow elliptical orbits just like the planets, except more elongated (eccentricity higher). A few comets that come from deep space are on hyperbolic orbits and are very fast-moving, they visit once and never come back because they have enough kinetic energy to escape again.
Asteroids are the celestial bodies found in between the spaces of the planets of the solar system. But comets are mysterious bodies that go far away from the known solar system and come back once very rarely.
Comets come from the Oort cloud and the Kupier Belt
First they study the subject, then they come up with questions that other people may want to know the answer to. After that, they use their studies and knowledge of physics to come up with a believable and reasonable way that something could be what they think it is.
Comets are solid pieces of rock that are in long elliptical orbit around the sun. They occur because pieces of other space objects (asteroids, moons, planets, etc.) were knocked off into this path, and the path just happens to come close to the Earth.
They are from extreme outer parts of the solar system (known as "Kuiper belt") and from a huge cloud of comets lying far beyond the orbit of Pluto, completely surrounding the Sun (known as "Oort cloud").
