Short-period comets, which orbit the Sun in 200 years or less, are usually Kuiper Belt objects, while long-period comets that take hundreds or thousands of years to orbit the Sun generally come from the Oort Cloud. Long-period comets are thought to come from the nearly spherical Oort Cloud even further out, which get slung inward by the gravitational pull of passing stars. [CDATA[ Comets are also known as the 'Dirty Snowballs' of Space. Answer: the Kuiper Belt and the Oort Cloud. Do they get tangled up in the oort clouds of other stars?

The time that comet's … Sometimes known as p…, CONCEPT Longer period comets are thought to originate from a theoretical region called the Oort cloud. To answer this question, we must reconstruct the orbit of comets before they enter the inner solar system for the first time, thus before the disturbances by the gravitational attraction of the most massive planets are felt. They are small icy objects that release dust or gas in space and orbit the Sun. 2. This has come to be known as the Oort Cloud. Most bright new comets, such as Comet Hale-Bopp, come from the Oort cloud and have orbits that are highly inclined with respect to Earth's orbit. Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA). Short period comets and long period comets. Like planets, some comets orbit the sun on a predictable schedule. (You can unsubscribe anytime). In this picture, the solar system is buried deep within the cloud. Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates.

The isotropic comets would come in, go around the sun, come out, and every once in a while one would happen to get close to a giant planet as it was coming in, and that giant planet would alter the orbit and pull it into the plane of the solar system, and so this was an evolutionary effect. viewed as planets.
