Comets

It proved that Isaac newton's Theories Of Motion And Gravity are correct.

Comets are icy bodies in space that release gas and dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them dirty snowballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more.

It was seen in many regions of the world, and is depicted on the Bayeaux Tapestry (Norman Conquest of England). It was a bad omen for Harold II but a good omen for William the Conqueror.

It is also noted in Irish annals of the time and may have been recorded by Native American tribes such as the Chaco tribe of New Mexico.

If the bodies are small enough they burnup in the atmosphere from friction and appears as shooting stars, and nothing reaches the ground.

If they are larger they heat up tpo very high temperatures on entering the atmosphere and impact the earth wth great force, making a crater - such as the ones seen on the moon. Very few of the bodied which enter the atmosphere survive the burn-up.

Many cultures have superstitious beliefs about comets and asteroids. The Philippines do not seem to share superstitions of comets and asteroids.

While it's a fun superstition, there is no scientific evidence to support the idea that your wish will come true if you sneeze. Sneezing is a reflex that helps clear your nasal passages and is not connected to wish fulfillment.

· One-tailed test looks at the probability that the sample mean was either "greater than", or "less than or equal to"

· Two-tailed test, sees if two means are different from each other (ie from different populations), or from the same population and tries to establish "equal to" or "not equal to

from the greek word comet, meaning "to comet"

Dr. Fred Whipple came up with the idea that comets are "dirty snowballs"; primarily ice and frozen gasses, holding a large quantity of dust, pebbles and rocks.

If the evidence hadn't supported his theory, he would have had to go back and come up with a different theory. That's the way science works - or at least, is SUPPOSED to work.

Tail of the Sun happened in 1996.

St. Judy's Comet was created in 1973.

The second name of functional affixes is "grammatical affixes." These affixes serve a grammatical purpose in a language, such as indicating tense, number, or case, as opposed to carrying lexical meaning like content words. They include prefixes, suffixes, infixes, and circumfixes that modify the meanings of root words.

"Dynamically stable, non-expanding or non-stretching Universe models; space does not 'expand' with these models."

"Do not confuse with Steady-state models which employ space expansion."

about 2010 early-midsummer Nibiru and his comet should enter previously known Sun System territory. Nibiru planet will pass 'quiet', however comet will shake human civilization to the grounds. Yet this is just the beginning...

It is a meteorite.

Some with fear. Comets, which are called that because they appear to be "hairy stars," suggest that there are big changes in the otherwise stable heavens and this can be very upsetting. We know today that comets are relatively small, relatively common, and - unless one should actually hit the Earth, which is not very likely - pretty harmless. Probably because a big event in the sky seemed as though it should be connected with a big event on Earth, back during the fear period comets came to be associated with the death of kings. No everybody believed this. When the Roman Emperor Vespasian was told about a comet, he joked that since it was so hairy, it couldn't be a message for him, as he was bald.

The next predicted appearance for both Comet 2P/Encke (also known as the Red Dragon) and Comet 29P/Schwassmann-Wachmann 1 (also known as Woodworm) is uncertain as they have irregular orbits and may not be visible again for several years. It is recommended to check with astronomical forecasting resources for the most up-to-date information on their visibility.

No collision between comets has ever been observed. Considering their small

size, such collisions are very improbable. And considering that a comet emits

no light and most of its orbital revolution takes place in the outer solar system

where it cannot be observed, the probability of our observing such a collision

is virtually zero.

Comet Swift-Tuttle was discovered on July 16, 1862 by astronomers Lewis Swift and Horace Tuttle independently.

Are you asking how big the crater would be if it struck the Earth? In one sense, it would depend on the size of the comet and the speed; in another sense, it might not matter at all.

The kinetic energy of any object is the mass times the velocity squared. Calculate the approximate mass of the comet, multiply it by the collision speed. If the comet were to come from behind, the impact velocity would be lower than if the comet hit us "head on". Whatever the comet's velocity, you would need to add the Earth's escape velocity; any object falling to Earth from space will have a additional velocity from Earth's gravity, which is 7 miles per second, about 25,000 miles per hour.

Here's why it really wouldn't matter; if the comet is big enough and fast enough, it won't create a crater; it will re-make the Earth itself. The comet could punch THROUGH the crust of the planet, releasing the magma, the liquid rock in the mantle. If it's big enough, it could wipe out humanity, and many other species on Earth.

An ion tail is a stream of charged particles, primarily ions, that are ejected from a celestial body, such as a comet, when it approaches the Sun. This phenomenon occurs due to the solar wind and radiation pressure, which strip away particles from the comet's nucleus. The ion tail typically points directly away from the Sun, as it is influenced by the solar wind's magnetic field. It is distinct from the dust tail, which is made up of larger, uncharged particles that are also released but follow a different trajectory due to their mass.

it can be about 1 foot long to 60 feet long!

You would have to see a dermatologist or plastic surgeon to find out but depends on severity.

The tail is the result of dust and games that are spread by dolor winds
