Comets

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

A tailwind is a wind that blows in the same direction as the movement of an object, such as an aircraft or a vehicle. It can enhance speed and fuel efficiency by providing additional thrust. In aviation, tailwinds are advantageous during takeoff and landing, as they reduce the distance required for these maneuvers. Conversely, a headwind blows against the direction of travel and can hinder performance.

The shape of a comet's path is an oval.

If u are an eighth grader, your science teacher will recommend u to use the word "ellipse" instead of oval ~ Thank You.

or "elliptical"

Early Man first noticed comets. Comets were around long before humans.

I am not sure exactly for how long you can see it. However, for most of its orbit, it is very far away, and therefore - and because it is a fairly small object - it is very faint.

Comets are composed of a mixture of ice, dust, and gases. The main gases found on a comet are water vapor, carbon monoxide, carbon dioxide, and methane. These gases are released as the comet gets closer to the Sun and heats up, causing the ice to sublimate.

Bill Haley played the steel guitar, tenor banjo, and double bass as a member of Bill Haley and His Comets. He was primarily known for his role as the lead vocalist and rhythm guitarist in the band.

Meteoroids are small pieces of rock moving through space.

Meteorites are meteoroids when are large enough that strikes Earth surface.

A comet is made of ice and other materials and its tail points at the strongest point of gravity along its path. That means that while the tail will point in the direction of the sun most of the time, if it were to pass near a planet where there was a strong attraction it would point o wards the planet until the suns gravity was stronger again.

The comet's 'tail' always points away from the sun.

Comets originate from the Oort cloud, a spherical shell of icy bodies at the outer edges of our solar system. These comets can be perturbed and sent into the inner solar system where they become visible as they approach the Sun.

That is actually a very good question. I know this is not very much but I don't think nothing much would happen.

By sending space probes into the solar system and beyond, we are able to gather information close to planets that we would not be able to obtain through observations from earth. The probes are able to take and transmit pictures back to earth which are much more detailed. We have been able to detect objects we would not see from the earth and are able to gather more detailed information on the atmospheric composition and properties of various planets and moons.

yes, a specific name of a comet is a proper noun.

comet is a short vowel
