What is the difference between a comet and a meteor?

Comets and meteors are two completely different concepts.

First of all, they are different from each other, the comet comes from a radius of 105 AU from the Sun, and it contains billions of comets orbiting the Sun in every possible direction, and because of the slight gravitational pull of passing stars, it disturbs the comet's orbit until the distance of its perihelion becomes less than a few astronomical units, and when the comet then enters the solar system, the gravitational attraction of the planets in the solar system transforms this non-periodic comet into a new periodic comet (which will exist for thousands of years before it collapses). On the other hand, These forces can throw it completely out of the comet cloud, which is a meteor that is moving around the Sun, and as it passes near the Earth, the gravitational pull of the Earth changes its orbit and enters the Earth's atmosphere.

Secondly, the composition of the material is different: the composition of the comet nucleus is mainly ice and dust, so the comet is also called the "dirty snowball", while the meteor is the dust particles and solid masses (meteoroids) of interplanetary space

And they emit light in a different way: the light in the comet part is reflected by the comet's gas and solid particles, and the comet also has a form of light, which comes from the comet itself, and the comet's gas molecules absorb the sun's ultraviolet light and get energy, excite from the lower energy order to the higher energy order, and then when they jump back to the ground state, they release energy, emit radiation at the same frequency as when they absorb it, and they emit light, and the meteor burns violently against the atmosphere when it enters the earth's atmosphere, so it emits light.

If they have the opportunity to pass near the earth, it is possible to break into the earth's atmosphere at a speed of tens of kilometers per second, and the material on it is converted into heat energy due to the violent friction with the earth's atmosphere, causing the matter to ionize and emit a dazzling light, which is the meteor we often see.

Comet. A comet is a type of celestial body that orbits the Sun. Its orbit is a type of conic curve, which is elliptic when the eccentricity e is less than 1, parabola when e is equal to 1, and hyperbola when e is greater than 1.

If a comet orbits in an elliptical orbit, then it can orbit the Sun over and over again, and it is called a periodic comet. Periodic comets are divided into long-period comets and short-period comets with a limit of 200 years.

When the comet moves away from the Sun, it appears as a cloudy spot; When approaching the Sun, it is composed of a comet nucleus, a comet, and a comet tail. The nucleus is composed of dense solids and can account for up to 95% of the total mass of the comet; Comet is formed by the volatilization and sublimation of coma nucleomaterial, which is cloud-like; Under the "blowing" of the solar wind, comets can produce large, extremely low-density comet tails. Because the main body of the comet The composition of the comet's nucleus is mainly ice and dust, so the comet is often called a "dirty snowball".

Comediats are generally larger in size and move slower.

Meteors are relatively small in size and move at a high speed.

1. Different compositions: Comets are mainly composed of ice and dust, while meteors are composed of dust particles and solid blocks in interplanetary space.

2. The principle of luminescence is different: the gas molecules of the comet absorb the sun's ultraviolet light and obtain energy, excite from the lower energy order to the higher energy order, and then release energy when jumping back to the ground state, emitting radiation of the same frequency as the absorption, thus emitting light, while the meteor is burning with the atmosphere violently when entering the earth's atmosphere to emit light.

3. Comets have a certain trajectory in the universe, while meteors do not.

Comet: A comet is a unique cloud-like appearance of a celestial body that moves around the sun and its brightness and shape change with the solar distance. Comets are divided into three parts: the nucleus, the coma, and the tail.

The comet nucleus is made up of icy material, which sublimates as the comet approaches the star, forming a hazy comet and a tail of thin material around the ice core. The comet has a very small mass and density, and when it is far away from the sun, it is just a "dirty snowball" of frozen ice cubes such as water, ammonia, methane, etc., and many solid dust particles. When approaching the Sun, the comet is broken down into a head and tail by solar radiation, which resemble a broom.

Summary. Good evening, dear dear, the answer to your question is as follows: comets are not meteors<>

Comets and meteors are not the same, comets and meteors are two different concepts. <>

1. A comet is a long-period celestial body that usually consists of ice and dust. They orbit the sun in the solar system and are often seen in interplanetary space. When the comet is close to the Sun, the Sun's gravitational pull attracts some of the ice and dust to the comet's surface and makes it brighter.

This process is called "comet tailing", and it is often one of the most striking features of comets. ,<

2. A meteor is a short-lived celestial body, usually a trail of light produced by a block of material (meteoroid) in interplanetary space that breaks into the Earth's atmosphere and burns up. As meteors pass near the Earth, they produce intense light and sound, leaving behind a long trail of smoke <>

Meteors are usually created as a result of material from Earth being carried into space, and they rub violently against the atmosphere as they enter the atmosphere, resulting in bright lights and sparks.

Are comets meteors?

Dear, their composition is also different from Li Peiming, oh <>

The commet material is mainly composed of water, ammonia, methane, cyanide, nitrogen, carbon dioxide and other non-solids, and the comet nucleus inside the comet is composed of water, carbon dioxide (i.e., dry ice), ammonia and dust particles condensed into ice. <>

The most abundant elements in meteors are iron, nickel, sulfur, silicon, cobalt, calcium, oxygen, etc., and are mostly solid substances.

His life cycle is also different: the age of the comet bench is close to that of a celestial body in the Liquid Tung universe, and the life cycle is very long, taking Halley's Comet as an example, from the historical records of mankind, Halley's Comet is more than 2,500 years old, in fact, its age is more than a million years old<>

Meteors begin to die out when they form meteor phenomena, and the whole process takes only a few hours, a very short <>
