(astronomy) a relatively small extraterrestrial body consisting of a frozen mass that travels around the sun in a highly elliptical orbit
A celestial body consisting mainly of ice, dust and gas in a (usually very eccentric) orbit around the Sun and having a "tail" of matter blown back from it by the solar wind as it approaches the Sun.
A celestial phenomenon with the appearance given by the orbiting celestial body.
Origin: From comete (French: comète), from cometa, from κομήτης, referring to the tail of a comet, from κόμη.
a member of the solar system which usually moves in an elongated orbit, approaching very near to the sun in its perihelion, and receding to a very great distance from it at its aphelion. A comet commonly consists of three parts: the nucleus, the envelope, or coma, and the tail; but one or more of these parts is frequently wanting. See Illustration in Appendix
Origin: [L. cometes, cometa, from Gr. comet, prop. long-haired, fr. to wear long hair, fr. hair, akin to L. coma: cf. F. comte.]
A comet is an icy small Solar System body that, when close enough to the Sun, displays a visible coma and sometimes also a tail. These phenomena are both due to the effects of solar radiation and the solar wind upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust and small rocky particles. Comets have been observed since ancient times. Comets have a wide range of orbital periods, ranging from a few years to hundreds of thousands of years. Short-period comets originate in the Kuiper belt, or its associated scattered disc, which lie beyond the orbit of Neptune. Longer-period comets are thought to originate in the Oort cloud, a hypothesized spherical cloud of icy bodies in the outer Solar System. Long-period comets plunge towards the Sun from the Oort cloud because of gravitational perturbations caused by either the massive outer planets of the Solar System, or passing stars. Rare hyperbolic comets pass once through the inner Solar System before being thrown out into interstellar space along hyperbolic trajectories. Exocomets, comets beyond our solar system, have also been detected and may be common in the Milky Way Galaxy.
Chambers 20th Century Dictionary
kom′et, n. a heavenly body with an eccentric orbit, having a definite point or nucleus, a nebulous light surrounding the nucleus, and a luminous tail preceding or following the nucleus.—adjs. Com′etary, Comet′ic.—ns. Com′et-find′er, a telescope of low power used to search for comets; Cometog′raphy; Cometol′ogy. [Gr. komētēs, long-haired—komē, the hair.]
The Nuttall Encyclopedia
a member of the solar system under control of the sun, consisting of a bright nucleus within a nebulous envelope, generally extended into a tail on the rear of its orbit, which is extremely eccentric, pursuing its course with a velocity which increases as it approaches the sun, and which diminishes as it withdraws from it; these bodies are very numerous, have their respective periods of revolution, which have been in many cases determined by observation.
