Comets

Halley's Comet is unique because it is one of the most famous comets known to humanity due to its regular appearance every 75-76 years. It is also the only short-period comet that is visible to the naked eye from Earth and has been recorded by humans for over 2,000 years. Additionally, Halley's Comet contains a nucleus made of ice, dust, and rocky material that gradually vaporizes as it gets closer to the Sun, creating its iconic glowing tail.

All of them. Even the short-period comets like Halley spend most of their time far out from the Sun; if they spent too much time in the inner system, all of their volatile gasses and ices would melt and sublimate away.

Small lumps of rock orbiting the sun are called asteroids.

Comet orbits are typically elliptical, meaning they are elongated and not circular like planet orbits. This can result in comets having highly eccentric paths around the Sun.

Comets are considered minor members of the solar system because they are smaller and less massive than planets and asteroids. They are composed of ice, dust, and rocky material, and often have highly elliptical orbits that take them far from the Sun. Comets are less numerous and play a smaller role in the dynamics and structure of the solar system compared to planets and asteroids.

One superstitious belief about asteroids is if an asteroid crashed in the surface of the earth, the climate will become hotter. Another is that asteroids will cause great harm to the earth when it passes.

Since science has studied asteroids, there are not many superstitions about them.

The length of the comet tail increases as it approaches the Sun because the heat causes volatile materials within the comet, like ice, to sublimate (turn directly from solid to gas). This process releases gas and dust particles, creating a long tail that points away from the Sun due to solar radiation and solar wind.

After Shoemaker-Levy,a comet that hit Jupiter.Maybe Shoemaker-Levy exploded at the surface of Jupiter and created a crater.Then after Shoemaker-Levy exploded at the surface of Jupiter it started to rain C4 bombs in Jupiter! Then Jupiter Blew up!!! BOOOM!!! The End.

Comets with short orbital periods are located in the inner solar system, typically with orbits that are less than 200 years. These comets originate from the Kuiper Belt or the scattered disk region beyond Neptune and are influenced by the gravitational forces of the gas giants in the outer solar system. They have more frequent appearances in our skies compared to comets with longer orbital periods.

Halley's Comet is not dangerous to Earth. It poses no threat to our planet and its orbit is well-studied, so we can predict its movements accurately. The last time it was visible from Earth was in 1986, and it is not expected to return until 2061.

A comet has a tail composed of gases and dust. As a comet travels through space, it heats up, causing the gases and dust to vaporize and form a glowing tail that points away from the Sun due to solar wind.

A meteor, nor asteroid would have enough mass so produce the tilt of the Earth.

It's not known for sure but a good suspect is the collision that occurred about 4.5 billion years ago, when Theia, a planet about the size of Mars, smashed into Earth. The impact, not only ejected material that created the Moon, but also could have destabilised the axis of the Earth.

Comets can affect Earth in the future and have affected Earth a great deal in the past.

Primordial Earth:

Primordial Earth, particularly in the first billion years of Earth, was shaped greatly by comets and asteroids and meteorites. Based on the known populations of comets now and projections to that earlier time, there is substantial evidence that half or more of all water on Earth was brought by comets.

Comet History:

Comets were a pretty unexpected apparition in the night sky before anyone knew what they were. For thousands of years people have seen them an taken them to be some kind of omen. History records great events and decisions connected with comets. Starting around the 1600s when science and astronomy were becoming separate from astrology and magic, comets were a helpful and motivating factor in stimulating the study of the cosmos. They have been such ever since.

We now know that comets are the source of meteor showers, an amazement to mankind throughout history.

There are not many reliable examples of large comets striking the Earth in recent history, but we can be quite certain that is has happened. Comet Shoemaker-Levi was quite spectacular when it hit Jupiter in 1993, leaving a disturbance in Jupiter's atmosphere that was larger than the size of the Earth.

Comet Future:

Still a a stimulus for scientific study, comets give us an opportunity to sample material from the most distant parts of the solar system. In particular, the source of most comets is from either the Kuiper belt beyond Neptune or the far more distant Oort cloud.

Comets are large enough to be dangerous.

Comet nuclei range from about 100 meters to tens of kilometers across. They are not solid like asteroids but composed of rock, dust, water ice, and frozen gases. Still, a large comet impact on Earth could be catastrophic for life and probably has been in the distant past. Unlike asteroids, they are less likely to appear suddenly and the probabilities for such a disaster are much lower for comets than asteroids.

Many comets in the Kuiper Belt are believed to be icy remnants from the early solar system, originating from beyond Neptune's orbit. These icy bodies likely formed near the giant planets and were scattered outward due to gravitational interactions, eventually settling in the Kuiper Belt.

For the last 4.5 billion years Halley's Comet has orbited the Sun.

The last time it was visible to the naked eye on Earth was 1986.

The next near pass is likely to be about 2061.

When a comet hits a planet, it can create a large impact crater and release a significant amount of energy. The impact may cause widespread destruction of the surrounding area, including triggering earthquakes and tsunamis. Additionally, the impact can release gases and dust into the atmosphere, which may affect the planet's climate.

Anything "can" turn into a black hole, as long as it is massive enough and dense enough. For example, Earth can turn into a black hole if all its mass is squeezed into a point about a centimeter in radius. The only reason that we don't see this happening is because you can't just make Earth denser than it already is (ever try to squeeze a chunk of putty?). Just because the odds of it turning into a black hole is very small doesn't mean it can't turn into one.

{ADDED} No, a comet cannot become a black hole. It is far too small and light (low mass), and loses material every time its orbit brings it relatively close to the Sun - the characteristic tail is that lost material, which like the head, reflects Sun light so is visible. The only objects cable of becoming black holes are the extremely dense cores of very, very large stars that die as supernovae, and even then, not all them become black holes.

The Russians named their space probes that visited Halley's Comet in the mid-1980s as Vega 1 and Vega 2. These probes were part of an international effort involving the Soviet Union, the European Space Agency, and other countries to study the famous comet.

Far out in space, the comets tail is short. As it approaches the Sun, the heat melts away some of the ice covering the surface. As it evaporates into space, a tail is formed behind the comet. Always, the tail is facing away from the sun. This is why, when we see comets, their tails are almost as long as they get.

Superstitious beliefs about comets varies between different cultures. The most common superstitions are; tragedy, success in war, increase in fertility, impending judgment and a future catastrophic event.

wanna see a comet? well

step 1: take a look at the forcast and make sure a night will be clear & no rain

step 2:get a tarp & sleeping bag and suppleis (NO TENT) and go to a place were you can see the sky really well.

step 3: put the tarp on the ground and wait till night to put the sleeping bag

step 4: chill at that place till night then drink a whole bunch of cofee (if your alowed)

step 5:now just get in your sleeping bag on the tarp and watever extra blakets you brought and wait

step 6:you''l see some stars but the sooner or later you'll see a comet (shooting star, make a wish!)

The above steps could be useful to you.. if you want to see a meteor.

Which is way more likely to happen than the sighting of a comet. All you really need to see a meteor is to be in a considerably dark area.. next to the ocean of a big lake works pretty well. The idea is to get away from as much light as possible.

In order to see a comet you generally would need to do some research to try to predict the passing of one (they orbit the sun) and a high quality telescope. Even if you can manage to do these things, comets are very unpredictable they can brighten or fade, lose its tail.. or even gain another, and it can ever break apart all together. Unless you have a connection to NASA it will be very difficult to know which comets are still kicking. If it is something you are really interested in.. try getting in contact with some one from the head of a university with a decent astronomy program.

In Stanley Kunitz's poem "Halley's Comet," he reflects on the rare occurrence of the comet passing by Earth only once in a lifetime. The poem contemplates themes of time, mortality, and the beauty of fleeting moments. Kunitz uses the comet as a metaphor for the transient nature of life and the importance of cherishing each moment.

No, a comet's tail always points away from the sun regardless of the comet's direction of movement. This is due to the solar wind pushing gas and dust particles away from the comet's nucleus, creating the tail that always faces away from the sun.

The Hale-Bopp Comet will appear in the inner-solar system in approximately the year 4377.

This is due to on April 1996 the comet passed within 0.77-0.771 AU of Jupiter, this distance is close enough for the comet's orbit to be affected by the planet's gravitational force.
