Comet is one object in the solar system orbit the sun. Sublimation is the gas when approaching the Sun. Cause the dust and gas surrounding hazy. And fry until it stretches out to the tail.A comet nucleus or center. "Dirty snowballs" composed of ice. Carbon dioxide, methane, ammonia and dust mixed together with hard rock. With diameters ranging from a few kilometers to tens of kilometers
.Long orbital period of the comet is different in several ways. Since periodic orbits periodic orbit only a few years from 50 to 100 years to hundreds or thousands of years. Some believe that the comet had passed through the center of the solar system only once.Comets with short orbital period, it is believed that it was originally a part of the Kuiper belt beyond the orbit of Neptune out. Most comets with long orbital periods may come from other sources at a distance from our sun a lot.These comets gravity disturbance from the outer planets. (Instances of objects in the Kuiper Belt) from other stars nearby. (Instances of objects in the Oort cloud), or from the collision. Move it closer to the sun.However, until very old comet that can sublimate into gas until it had ceased to be the condition was similar to the asteroids. Near-Earth asteroid many believe it was a comet before
.May the year 2009, it was reported the discovery of a comet, then 3,.Length 648 [1], several hundred of these a short period comets. The discovery is still ongoing. The discovery, which then was only a small fraction of the entire comet.Comet can be seen with the naked eye it appears on average at least once a year I [3], many of the visible light is only
.Comet bright enough to be easily observed by the naked eye, often called the Comet (England.great comet) is also a type comet narrowly missed the sun. Which tends to crumble when it approaches the Sun. Largely as a result of gravity. A source of various meteor. The moon and comets with orbits thousands unstable
