A comet is a small body orbiting our Sun, usually at great distance from Earth and with a highly elliptical orbit. They are composed of 'ices' and dust. As a comet approaches the inner solar [..]

(n) (astronomy) a relatively small extraterrestrial body consisting of a frozen mass that travels around the sun in a highly elliptical orbit

A large mass of ice and dust that has an orbit around a star.

c. 1200, from Old French comete (12c., Modern French comète), from Latin cometa, from Greek (aster) kometes, literally "long-haired (star)," from kome "hair of the head" (compare k [..]

A gigantic ball of ice and rock that orbit the Sun in a highly eccentric orbit. Some comets have an orbit that brings them close to the Sun where they form a long tail of gas and dust as they are heat [..]

celestial object made up of ice, gas, and dust that orbits the sun and leaves a tail of debris.

An object which circles the sun in a non-circular orbit. Commonly made up of a large mass of rock debris and ice. Basically, a giant snockball from space.

To dream of this heavenly awe-inspiring object sailing through the skies, you will have trials of an unexpected nature to beset you, but by bravely combating these foes you will rise above the mediocre in life to heights of fame. For a young person, this dream portends bereavement and sorrow.   

A comet is a “dirty snowball” of ice and rocky debris, typically a few miles across, that orbits the Sun in a long ellipse. When close to the Sun, the warmth evaporates the ice in the nucleus to form a coma (cloud of gas) and a tail. Named for their discoverers, comets sometimes make return visits after as little as a few years or as long as tens o [..]

Frozen masses of gas and dust which have a definite orbit through the solar system.

Small frozen masses of ice, dust, and gases that travel a definite path through the solar system.

A small mass of ice and dust that revolves around the Sun in a highly elliptical orbit.

A comet is a relatively small solar system body that orbits the sun. When close enough to the Sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tai [..]

Comet is a programming technique that enables web servers to send data to the client without having any need for the client to request it. It is a push technique to use instead of polling to have clie [..]

A celestial body that orbits the Sun and is formed from dust, ice, rock fragments, and frozen methane and ammonia (Lesson 30)

(n.) An interplanetary body, composed of loosely bound rocky and icy material, that forms a glowing head (coma) and extended tail when it enters the inner solar system.

a ‘dirty snowball” orbiting the Sun. It is a mixture of ices, frozen gases, rock, and dust left over from the formation of our solar system.

A large cylindrical pumped star that leaves a sparked tail.

a body of dust, frozen water and gases falling sunward from the outer regions of the solar system. Comets become visible when they approach the Sun, as sunlight evaporates their upper layers and creat [..]

A pellet of composition which is propelled from a mortar or shell and produces a long tailed effect. Large comets are constructed much like aerial display shells, with attached lift charge ready for l [..]

Trailing behind another tramp or hobo, one who tries to catch up.

A celestial body, observed only in that part of its orbit that is relatively close to the sun, having a head consisting of a solid nucleus surrounded by a nebulous coma up to 2.4 million kilometers (1 [..]

A luminous member of the solar system composed of a head or coma, at the center of which a nucleus of many small solid particles is sometimes situated, and often with a spectacular gaseous tail extend [..]

is a celestial body moving about the sun consisting of a central mass surrounded by an envelope of dust and gas that may form a tail that streams away from the sun.

A body of small mass but large volume, compared to a planet, often developing a long luminous and partly transparent tail when close to the Sun.

A ball of rock and ice, often referred to as a “dirty snowball.” Typically a few kilometers in diameter, comets orbit the Sun in paths that either allow them to pass by the Sun only once or that repeatedly bring them through the solar system (as in the 76-year orbit of Halley's Comet). A comet’s “signature” long, glowing tail is formed when th [..]

Cooperative program for Operational Meteorology, Education, and Training

Solar system body, consisting of a solid nucleus made up of rock and ice. There are two comet sources: the Oort Cloud and the Kuiper Belt. As they near the Sun, comets give off an atmosphere in the form of two tails, one neutral and one ionized.

(astronomy) 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 approa [..]

 Colloquial An occasional lover who passes through one’s life semi-regularly, but without an expectation of continuity or a romantic relationship.

Type of broomstick flown by Cho Chang.

Icy body which orbits the Sun. Thought to be leftover planetesimals from the formation of planets in the outer Solar System. The small, solid nucleus consists of water and other ices coated with dark organic compounds. As the nucleus approaches the Sun, it vapourises, creating a coma and two main tails. These tails - one made of gas and one of dust [..]
