What are asteroids comets and meteors?

Asteroid comments and meteors are forms of interplanary debris Rocky and IC fragments left from the formation of the solar system they usually travel at a great distance from earth but we see them even with the eye when they near our planet 

Million of Asteroid Orbit the sun usually in a built between the orbits of Mars and Jupiter a few brush past the planet Earth generally larger that than comets and meteor asteroids are chunks of Rock and metal that can rain from 100 yards to almost 600 miles in with comets sometimes listen to big dirty snowballs are made up of Rock eyes dust carbon dioxide Methane and other gases they originate in the cuper belt as comet journey toward the Sunday begin to defrost solar hit vaporizes eyes which forms a Halo of gas and dust call a comma around the comets nucleus approaching Mars comets may form tell some hundred of millions of my Lego meet your more commonly same from earth that asteroids are or comet are known to most a shooting star but they are actually not started

Villain asteroid hit soon if an asteroid hit ear it effects on our planet will depend upon it size Earth atmosphere usually protect this planet from asteroid less than 150 feet in diameter objects up to 3000 feet across create intense localised damage such impacts occur every few century asteroids more than 5000 feet across kul kick up dust and cause and impact winter such hits occur once or twice every million years the chicxulub creator in Mexico was probably the result of an asteroid impact 65 million years ago the dust produced may have caused a climate change that lead to the extension of the dinosaur to date astronomers have cataloged some 1541 potentially hazardous asteroid the none are believe to be on a collision course with Earth

Variations on the Meteor meteoroids meteors and meteoroids all represents different stages of interplanetary debris meteoroids are small chunks of Rock and metal piece of Asteroid bit of comet and rarely pieces of moon or Mars that Orbit the sun earth gravity sweeps up million of meteoroids most of them vaporize in a atmosphere living a visible trail of growing dust we call a meteor or shooting star meet your rights are meet your that make it through Earth atmosphere and reaches the ground media of appear on a regular basis in the night sky but they also with great reality in large number at certain Times Of The Year known as meet your shower there often name for the background constellation against which they appear

What is mean by short period comet a comet that make regular orbits around the sun every 200 year or less hells comet with its 75 or 76 year period is a short period comet

long period comet comet that makes regular Orbit around the sun every 200 year or more

Halley's comet is the most famous and brightest comet rehabili visible on earth it's reappearance in 1758 confirm to British astronomer edmonth hail 17 not 5 prediction of a 75 or 76 year period this colour image is an enhancement of 1910 black and white photography
