Comets

Comets are small solar system bodies that orbit around the Sun. They have a tail (trail of light) when traveling in space.

Why do comets tail always stream away from the sun?

User Avatar

Asked by Wiki User

Comet tails always stream away from the sun due to the solar wind, which is a stream of charged particles emitted by the sun. The solar wind pushes against the gas and dust particles in the comet's coma (a cloud of gas and dust surrounding the nucleus) and causes them to form a tail that points away from the sun.

There is no widely recognized public figure or well-known individual named Halley Barre in mainstream media or popular culture. It's possible that Halley Barre may be a private individual or a lesser-known public figure.

What part or parts of a comet come and go during a comet's orbit?

User Avatar

Asked by Wiki User

During a comet's orbit, the coma and tails are the parts that come and go. The coma is the glowing, fuzzy cloud around the nucleus that develops as the comet gets closer to the Sun. The tails, consisting of ion and dust tails, form as a result of solar radiation and solar wind pushing the coma's particles away from the nucleus. Both the coma and tails diminish as the comet moves away from the Sun during its orbit.

What happens to the comets tail as it passes the sun?

User Avatar

Asked by Wiki User

As a comet approaches the Sun, the heat causes ice and other volatile substances within the comet to vaporize. This forms a glowing coma (a cloud of gas and dust) around the solid nucleus of the comet. The solar wind then pushes this gas and dust away from the Sun, forming a tail that can stretch for millions of kilometers in the opposite direction of the Sun.

How do many comets change as they approach the sun?

User Avatar

Asked by Wiki User

As comets approach the sun, they undergo several changes. The increase in temperature causes the icy nucleus of the comet to vaporize, creating a glowing coma around it. This coma is often accompanied by a tail pointing away from the sun due to the solar wind's effects on the released gas and dust. Additionally, the intense heat can cause the comet to fragment or even disintegrate completely.

Is it true there was a huge comet that crash to north America 12900 years ago and that causes the wild fires?

User Avatar

Asked by Wiki User

There is scientific evidence to support the hypothesis of a comet or asteroid impact in North America around 12,900 years ago, known as the Younger Dryas Impact Event. However, the direct connection between the impact and widespread wildfires is uncertain. Wildfires can have multiple causes and are influenced by various factors, so it's challenging to attribute them solely to the impact event. Further research is still being conducted to understand the extent of the impact and its effects on climate and ecosystems.

Do Comet goldfish need heated water?

User Avatar

Asked by Wiki User

No, Comet goldfish do not require heated water. They are a cold-water species that can tolerate a wide range of temperatures, typically between 65-75°F (18-24°C). It is important, however, to provide them with a stable and consistent water temperature to ensure their well-being.

Does most comets have a circular orbit that keeps them in the space between mars and Jupiter?

User Avatar

Asked by Wiki User

No, most comets do not have a circular orbit in the space between Mars and Jupiter. The majority of comets originate from two regions in our solar system: the Kuiper Belt and the Oort Cloud. These regions are far beyond Mars and Jupiter, and the comets from these regions follow highly elliptical orbits that can take them close to the sun or far into the outer reaches of the solar system.

Was Halley's comet seen in 1834?

User Avatar

Asked by Wiki User

No, Halley's comet was not visible in 1834. Halley's comet has an orbital period of about 76 years, so it was last visible from Earth in 1986 and will next be visible in 2061.

What are 3 parts of a comet?

User Avatar

Asked by Wiki User

The three main parts of a comet are the nucleus, coma, and tail. The nucleus is the head of the comet, the coma is the middle, and the tail is the end of the comet.

Is it true that Asians are shorter and smaller than average?

Asked by Wiki User

Some races have an average height which is shorter than others. But there are always exceptions. The tallest man currently registered with Gunniess World Records is Chinese. However he has allegedly been overtaken by a Ukrainian who is still growing.

What size is the nucleus of a comet?

User Avatar

Asked by LooneyTunerIan

Any size is possible, though most of them are "small", at least compared to things like planets. Halley's Comet, for example, is about 15x8x8 km, which is quite large on a human scale ... most mountains aren't that big ... but still small compared to Earth itself or even the Moon.

What are the similarities between planets and comets?

User Avatar

Asked by Wiki User

  • Asteroids and meteors are made up of rocks or ice.
  • All cannot be seen without a telescope (Only comet has exception to that whenever it's orbit comes close to Earth such as Hailey's comet.

What happens when the Earth crosses a comet's orbit and encounters comet debris?

User Avatar

Asked by Wiki User

what would happen if a comet collided with our planet?

I can visualize it harming the atmosphere before it makes its crash,

perhaps that was the cause of extinction of life years ago,such thing may cause eruption of volcano that sends intense level of atoms in the ozone layer and stop the penetration of sun rays,as a consequence, temperature drop down ,rains will be more repeated that the level of the sea would rise,an other effect of such collision is earthquake that could eradicate ail forms of existence all these are enough reasons for scientists to search more and more how to escape such a tragedy

What is the reason why comets fell down?

User Avatar

Asked by Wiki User

"Down" is the direction of the greatest mass, which, in the Solar System, is the Sun. The reason ALL comets haven't fallen into the Sun is that there also have angular momentum, which results in them falling AROUND the Sun.

How you can reduce shrinkage in BOPP film?

User Avatar

Asked by Wiki User

The shrink-ability results from polymer chains under stress which upon heating, this stress is released and polymer chains have more freedom to move around and stabilized under more relaxed state upon cooling.

Moreover, The shrink-ability of BOPP film is determined mainly by the orientation process.

Thus, by decreasing the stretching in the machine direction (MD), the shrink-ability in MD will be reduced.

Same for TD.

Were does the comet Halley go after it comes to earth?

User Avatar

Asked by Wiki User

Halley's Comet never comes to Earth. The comet - as with all astronomical bodies - follows its own orbit, falling endlessly through the solar system.

Halley's Comet is currently a little further from the Sun than the orbit of Neptune, moving very slowly outward from the Sun. It will linger there, reaching the peak of its orbit in about 15 years, before beginning its long slow fall back into the inner solar system.

Why are comets not seen very often in the night sky?

Asked by Wiki User

Comets have wide orbital paths, they are great balls of ice and dust that can take hundreds of years to complete one orbit.

Is it possible for a comet to have no tail at its perihelion?

User Avatar

Asked by Wiki User

the answer is idk

Yes, it does have brighter and longer tail, because during its closest approach to the sun, it was most effected by the sun (evaporating the more water from the comet).

When it was further out, when the sun is much further, it will gradually become cooler, no ice evaporating too space, and no tail.

Why does a comet appear to have a fiery look?

User Avatar

Asked by Wiki User

Comets are made of ice, rock, cosmic dust, ammonia, carbon dioxide, methane ice and water. Density will vary depending on it's exact composition. Being that its primary component is water ice, it's specific density will be very close to 1. That is a comet is likely just less dense than water. A large comet if landed softly in the ocean would probably float.
