Comets

Comets hitting the Sun are rare events due to the vast distances involved in the solar system. The Sun's intense heat and gravity typically vaporize comets before they can impact it directly. If a comet were to hit the Sun, it would likely disintegrate completely or be pulled into the Sun, without causing any significant disturbance.

The dense section of a comet's head is called the nucleus. It is composed of ice, rock, and dust, typically ranging in size from a few hundred meters to tens of kilometers. The nucleus is the solid core of the comet from which gas and dust are released to form the comet's coma and tail when it gets closer to the Sun.

Yes. Every body in this world wil die on the 12th. This is a very hard question for people to answer, but i am a scientist and it is my job to do hard work to discover the world. (i am also very smart). So enjoy the 1-2 years left of your life and don't think about the future.

That is all wrong. God has a plan for us, and anyone who says the exact date or year or time is wrong. I don't care if you're a scientist. God will save those who believe in him in the rapture. Trust me. We are meant to have a long life.... (except those who aren't believers, *Cough* *Cough* Mr. Stupid Scientist)

Ignore the previous answer, as forcing a religious belief onto somebody without any leeway for logical answering is just kinda unfair (no offense to any religious people, and hopefully not the previous answerer). Put simply: no, we won't (and if the first answerer really was smart, s/he would know proper grammar. Anyway, we won't die. 2012 signifies the turn of the Mayan calendar cycle, and it is said that 'whoever lives through this cycle is lucky'. This doesn't mean that it's lucky to survive it, but more that living during a time in which the cycle changes brings luck. Nobody will die (well, no more than usual on a set day), so don't freak.

Comas form around comets when they approach the Sun and heat causes volatile compounds within the comet to vaporize and escape, creating a surrounding cloud of gas and dust. This process is known as outgassing, and it gives comets their characteristic glowing halo.

"Periodic" comets reappear at predictable intervals, such as Haley's Comet.

Some comets are never seen again. A few crash into the Sun and are destroyed; a few crash into other planets, such as the Shoemaker-Levy comet that hit Jupiter. Many comets have such long periods, in terms of thousands of years, that no records exist that anyone ever saw them before.

The sparse sphere of comets that surrounds the sun and planets is known as the Oort Cloud. It is a vast region of space that is thought to contain billions of icy objects and comets. The Oort Cloud is located far beyond the orbit of Pluto, extending up to about 1.6 light years from the sun.

They have a tail, nucleus (the physical mass that is flying through space). Here s the astronomical sign for comets: ☄

There are most recognizable by their hair like tail.

Looking up to the sky on a starry night you see a comet streaking through the heavens. It looks like a small fuzzy ball with a long hair-like tail. Other times a comet looks like a white streak.

There are three main characteristics to a comet's appearance which are: the nucleus, the coma, and the tail. The nucleus is the solid central part of the comet. This is the actual mass that is traveling through space. The nucleus of a comet is dark, is potato-shaped in many comets, and resembles a dirty iceberg. A comet coma forms when the nucleus evaporates and a large cloud expands around the comet center. This cloud is called the coma. This spherical cloud gives the comet the appearance of a fuzzy ball. The most recognizable characteristic of a comet is its tail. The comet tail also forms when the nucleus evaporates, releasing gas and dust. Both the gas and dust form their own distinct tail. The trail of dust is left behind the comet in its orbit forming a curved tail called the anti-tail or dust tail. The ion tail of a comet is composed of gases and points towards the sun. A comet's tail is what comets are known for. Without a tail it would just look like a spot of light moving across the sky.

Comets can be many different colors including silver, blue, purple and gold at the end of their tail. Comets are usually blue or white at the front part. The color of the comet depends on its distance from the sun.

EVERYTHING is ALWAYS moving. Nothing stands "still"; in fact, there is no such thing as "still".

The Earth is spinning; at the equator, you would be moving at 1,200 miles per hour, without noticing it - because the air is ALSO moving that fast. The Earth is moving, too, at about 66,600 miles per hour in its orbit around the Sun.

The Sun is moving, too, because the entire galaxy is spinning once every 200 million years or so. The Milky Way galaxy is also moving, although we can't be sure exactly which way or how fast.

Comets are orbiting the Sun, speeding up as they get closer to the Sun and slowing down as they move away.

The recession of the early 2000s began in March 2001 and lasted until November 2001. It was mainly triggered by the collapse of the dot-com bubble and exacerbated by the September 11 terrorist attacks.

Aside from the regular short-period and dim comets, not noticed by the average person (such as Comet Encke or Comet Tuttle 1) the next comet we can be reasonably sure of seeing is good old Comet Halley, next scheduled to appear in July of 2061. But there will almost certainly be at least one or two large, bright comets visible on earth before then - we just don't know when they will be. Comets, even large, spectacular comets, are frequently just discovered about 4-9 months before they become a great display in the night sky. None meeting the criteria are in sight right now - but stay tuned.

A planet like Earth makes repeated trips around the sun and can be seen from Earth at regular intervals.

Halley's comet last appeared in 1986 - it's not due back in our part of space until 2062 ! Its orbit through our solar system takes about 76 years.

Comet Swift-Tuttle is a periodic comet with a nucleus primarily composed of rock, dust, water ice, and frozen gases such as carbon dioxide, carbon monoxide, and methane. When the comet approaches the Sun, these materials heat up and form a glowing coma and long tail as they are expelled into space.

Solar winds blow the debris of the traveling comet to make it appear it has a tail.

Astronomer Edmond Halley (1656-1742) mathematically predicted the return of Halley's Comet in1758, and established the periodicity of long-term comets.

It was named after Halley in 1759.

Edmond Halley was a significant figure in the field of astronomy for various reasons. He accurately calculated the orbit of the comet that now bears his name, predicting its return after 76 years. Halley also made contributions to the understanding of planetary motion and magnetism, laying the groundwork for future scientific advancements in these areas.

Comets are icy bodies that can have long tails when they approach the Sun, asteroids are rocky or metallic bodies that orbit the Sun, and meteors are small particles of rock that burn up upon entering the Earth's atmosphere. Each of these objects interacts with the Sun and planets in different ways.

Those are called comets. Comets are icy bodies that orbit the Sun and, when close enough, develop a visible coma (a fuzzy atmosphere) and tail due to the heat of the Sun evaporating their ice and gases.

A comet moves slowest when it is farthest from the sun in its orbit, known as aphelion. At this point, the gravitational pull of the sun is weaker, causing the comet to slow down.

Comets are typically found in the outermost layer of the Earth's atmosphere known as the exosphere. This layer extends from about 500 km to 10,000 km above the Earth's surface and is where the majority of comets orbit and travel.

its not the head of comet always faces de sun but its the tail that will b formed always away 4m de direction of sun. that's y u`ll c as if head is always towards de sun. n tail is formed by water vapour n dust from comets surface . as de comet moves around de sun a pseudo force called centrifugal force acts on these particles in de direction away from de sun so they flow in that direction n forms de tail which makes de actual comet look like head which is always towards de sun.

Comets travel in long orbits around the sun, and they are made up of ice, rock, and dust. The tail of a comet forms when it gets close to the sun, causing the ice on its surface to vaporize and create a glowing trail of gas and dust.

the first comet discovered was in 3010 AD by mor ben-zvi

As a comet passes near the sun, it may leave behind a trail of debris consisting of dust and rock particles. These debris may form a meteoroid stream along the comet's orbit. Additionally, comets can also shed larger fragments or break apart, leaving behind fragments or new smaller comets in its wake.
