How often a comet reappears depends on its orbital period. Comets can be either short-period or long-period, with the orbital periods ranging from a few years to millions of years.


Short-period comets (those that have orbital periods of less than 200 years) originate in the Kuiper belt, beyond the orbit of Neptune. Long-period comets (those with orbits longer than 200 years) are thought to originate in the Oort cloud, a cloud of icy bodies from beyond the Kuiper belt.


Because of the wide range of their orbital periods, comets can be found in a number of places in the Solar System. Short period comets usually depart from the area of Kuiper Belt. Long period comets usually depart from the Oort Cloud on the boundaries of the Solar System. The comets themselves can be found anywhere along their orbits. The orbits are different for each of the comets. The exact position of a given comet depends on its orbit and time. Some comets do not have stable orbits and are thrown out into interstellar space after making only one pass.


Short-period comets originate from the Kuiper Belt.


Most comets travel around the Sun in elliptical paths. The time it takes a comet to make a complete orbit is called its period. Some comets have short periods of less than seven years. Others travel in such huge orbits that they pass near the Sun only once in thousands or even millions of years. As of 1995, 878 comets have been catalogued and their orbits at least roughly calculated. Of these 184 are periodic comets (orbital periods less than 200 years); some of the remainder are no doubt periodic as well, but their orbits have not been determined with sufficient accuracy to tell for sure. No comets seem to have approached the Sun from beyond the limits of the solar system. Therefore, all comets seen by astronomers are considered part of the solar system.


The second largest planet in the solar system and the sixth planet from the sun is the Saturn. It also has a comets named Saturnian Family of comets(a group of short-period comets) and Jovian(a larger family of short-period comets).


The primary difference between Halley's Comet and other known periodic comets is that Halley is the only significant comet with so short a period; it is possible to live long enough to see it twice. Most comets have periods in excess of a normal human lifespan.


Comets with a return period less than 200 years are arbitrarily called short period comets.No comets are currently known with an orbital eccentricity significantly greater than 1, so they are all considered to be solar system visitors.Some from the Kuiper belt, and some from further out called the Oort Cloud.The longest period comets may have return periods of greater than 1 million years, but maybe their orbits become so perturbed by other masses in their lifetime, that they never return to Sol.



Asteroids are minor planets, especially those of the Inner Solar System. However, between the orbital paths of Mars and Jupiter lie a region known as the asteroid belt. Many asteroids come from there, but most of them stay there. Short-period comets originate from the Kuiper Belt, just outside the orbit of Neptune, while long-period comets are thought to originate in the Oort cloud.


-- Despite where they come from, some comets have different mass qualities. While some are long-term comets, some are short-term. Short-term period comets originate in the Kuiper belt or it's "shattered disc", which is around the orbit of Neptune. Long-term period comets originate in Oort cloud, which is a cloud of icy bodies in space.



Every comet is different. We divide comets into two broad categories; "short period" comets, with periods less than about 200 years, and long-period comets, with longer intervals between passes. Since our recorded astronomical history only goes back about 400 years, there are probably a great number of long-period comets floating far out in space and only just now starting to fall into the inner solar system.


Short period comets have a period of less than 200 years Long period comets have a period of more than 200 years.



It's almost impossible to give a definitive answer. Some comets only have short orbital periods (less than 300 years), while others have been calculated to take thousands of years to return close to the Earth ! As an example, Halley's comet returns roughly every 76 years (last time was in 1986, the next time will be around 2062). At the other end of the scale, comet McNaught is estimated to take around 92,000 years to travel once around the sun !


Collisions between objects in the Kuiper Belt produce fragments that become comets. The comets are known as short-period comets. Short-period comets take less than 200 years to orbit the sun. Therefore, they return to the inner solar system quite frequently, perhaps every few decades or centuries. Short-period comets also have short life spans. Every time a comet passes the sun, it may lose a later as much as 1m thick.


There are two types of comet, short period and long period. Short period comets complete one orbit of the sun in less than 200 years, long period in more.


Scientists believe most comets come from the Oort cloud. The Oort cloud is a large cloud of comets that lies beyond Pluto's orbit.


comets are only seen for about a few months when thay get closer to the sun on their journy around the soll a systam


They move a short period of time because hopping is tiring to the legs


Short term comets are comets that make one orbit every 200 years or less, some very short term comets can orbit once every 20 years or less. Long term comets may take anything between 200 years to thousands, tens of thousands or millions of years to make one orbit of the sun.


Comets and Asteroids travel the solar system for the same reason the plants do, they just follow a different path. Asteroids are mostly orbiting the sun in between Earth and Mars in the Asteroid belt. While planets follow an elliptical path, comets follow a more elongated one. Comets that orbit the sun once every 200 years are called short period comets, for example the comet Haley. The comets that have orbital periods longer than 200 years are called long period comets and spend more time out by the Oort cloud. Since the sun is the body in our solar system with the greatest amount of mass it attracts all other bodies with smaller masses to it. One important formula to keep in mind is Newtons Universal law describing gravitation, F= G(M*m)/r^2, Where F is the attractive gravitational force between two objects of mass M and m separated by a distance r. G is just a constant. This is why comets and asteroids travel around the solar system and more specifically our sun!:)


It depends on the comet. You can see comets when they are making their swing around the sun, if they are large enough and if their orbital path brings them close enough to earth. Many small comets are not visible, and we cannot see any of them when they are far enough from the sun. Halley's is probably the best known comet, and it was visible at its last approach to the sun in 1986. I had the good fortune to see it and it was beautiful, but by all indications this was not as spectacular as its previous appearance 75 or 76 years earlier. It will appear again in 2061 because it is a short-period comet. Other comets can take thousands of years to return to our vacinity.
