Comets

a meteorite is a stone that has reaches from outer space. a comet is a moving rock across the sky and an asteroid is a big rock that revolves around the sun between mars and jupiter

since comets are big, dusty snow-balls, it doesn't much protection from most of a comet, and the atmosphere takes care of that.

However, in the case of a direct hit by the head of a comet ... kerpow!

The earth wouldn't really be damaged, but the little things (like us) would be.

The vast disk of icy comets near Neptune's orbit is called the Kuiper Belt. It is a region of the outer Solar System that contains numerous small icy bodies and serves as a source of short-period comets.

Comets and meteors were formed, along with the rest of the solar system, about four and a half billion years ago.

Comet Cleaners offers dry cleaning and laundry services, whether the order is commercial or personal. Comet Cleaners is a certified environmental dry cleaner.

Comet cleaner is used for surface cleaning of non-porous materials such as porcelain, stainless steel and fiberglass. It won't scratch any surfaces and does not contain bleach.

The short answer is No, Halley's Comet will not be around when the Sun becomes a red giant. When a comet gets close to the Sun (formally called a perihelion passage), the comet's surface gets heated up, and a layer on the surface sublimates and is lost into space. This means that a comet gets smaller over time, since it loses mass each time it swings by the Sun. As a general rule, a comet whose perihelion is one AU (the same as the average Earth-Sun distance) will lose about one meter of its surface during each perihelion passage. Comets that get closer to the Sun than 1.0 AU may lose several meters of their surface during each perihelion passage. Halley's comet is currently on an orbit with a perihelion of 0.59 AU, so it probably loses several meters from its surface during each perihelion passage. The average diameter of Halley's Comet is about eleven kilometers, so after a few thousand more perihelion passages, none of it will remain. Each orbit of Halley's Comet takes about 75 years, so it will be completely gone within a few hundred thousand years, at most. The Sun will become a red giant in about five billion years, so Halley's Comet would have sublimated out of existence long before then.

I am not aware of anything that is predicted to pass near the Earth in 2030.

The asteroid Apophis is predicted to make a very close approach to the Earth on April 13, 2029 (which is, by sheerest coincidence, Friday the 13th), coming within ab0out 15,000 miles of the Earth. This is actually closer to the Earth than most communications satellites! However, scientists are certain that it will not strike the Earth.

Seven years later, on April 13, 2036, the asteroid Apophis will again come close to the Earth; there is a VERY small chance that it will hit us on that pass.

However, there are many small objects that remain undetected in the solar system. Last week, in mid-November 2009, a 15-meter asteroid passed within a few thousand miles of the Earth. It was detected only 15 hours before its closest approach. A year ago, an asteroid about 20 meters in diameter was detected 18 hours before it impacted the Earth over east Africa. And last month, a small asteroid struck the atmosphere and exploded about 50 miles up.

The Earth is struck by thousands of meteoroids every hour of the day, totalling several TONS per day. Most vaporize without reaching the ground, becoming dust. A few survive the strike the ground, but only rarely do they cause any damage.

Comets are dusty pieces of ice and rock that partially vaporize when they pass near the sun. Meteoroids are pieces of rock, usually less than a few hundred meters in size, that travel through the solar system.

Because... they're mainly composed of ice and dust. When they get close enough to be affected by the Sun - the stream of particles forming the 'tail' is formed from ice crystals and dust particles.

An advantage of mining asteroids is that the asteroidal metals and minerals are concentrated in a small, easily accessible space and they are much purer in content.

Casey Comets was created in 1975.

Comet Electrical was part of Comet Group, which ended operations in December, 2012 Comet Electrical was known for selling electronics in stores in the United Kingdom

Comets are small, icy bodies that orbit the Sun. When a comet approaches the Sun, the heat causes its ice and other volatile substances to vaporize, creating a glowing coma and sometimes a tail that points away from the Sun due to solar wind. Comets are believed to be remnants from the early solar system and can provide important insights into its formation and evolution.

To find the Comet Medal in Sky Station Galaxy, you must head to the planet with the rolling Chomp. Begin riding the platforms past the checkpoint flag and keep an eye out for a Luma on a small planetoid nearby. Talk to the Luma to transform into Cloud Mario, then use the clouds to reach the top of the rolling Chomp planet to find the Comet Medal.

Superstitious belief of Korea about comet is that comet will be seen in the sky on June 15, 2019. According to the old belief, people believe that seeing a comet means it's time for them to die or something bad will happen to them.

But today, it has become popular among Korean people that there is no need to worry because this superstition of Korea about comet can only be seen once every few hundred years and therefore nothing serious will happen.

However, even if you don't believe in this superstition of Korea about comet I would suggest you do not forget your passport or any important documents when you go out on June 15th because by then people may think they are going crazy!

Thanks for reading my answer!

Good question,but NO comets do not really have lots of gravity to have a atmosphere.But they have two tails i'll tell you what they are called,one is a Rocky Tail while another is an ion tail that extends millions of miles into space. They also have a nucleus, which is basically the center of the comet. So hoped I helped ya!! :)

Halley's Comet

Comets are often thought of as visitors from other solar systems. Solitary travelers in space. Asteroids can and do exist as "belts" and are usually found in groups that can orbit a central sun very much like planets. Composition can be very different for both objects. Both follow prescribed orbits, hence we are able to predict/know the returning date for Haley's Comet.

Am not familiar with any data about asteroids with orbits as far reaching as comets.

Because comets follow a predicted orbit, and visit our solar system at regular times, they could be considered part of our solar system the same way as band of asteroids.

However, comets can and do leave our solar system and pass through others, so they are more visitor than permanent part of our solar system.

It was called Miss Mitchell's Comet and is also known as Comet 1847 VI.

Occasionally they enter the realm of the inner solar system and become visible .five kilometers is a typical size -- but some are much larger.

I don't think it would stretch out. The tail is the result of the comet evaporating; the tail goes away from the Sun, as a result of the solar wind.

Smaller.

Each time it passes the Sun, the comet boils off some of its icy gasses, and the dust is carried away from the comet by the solar wind. Light hitting the gas and dust cause the luminous "tail" of the comet.

In the long run, every comet will disintegrate as the Sun evaporates the ice that holds it together. The fact that we still see comets 4.5 billion years after the birth of the solar system indicates that there must be a vast reservoir of new cometary nuclei that occasionally fall into the inner solar system. This is the origin of the "Oort cloud" theory.
