This is a question that is greatly debated by astronomers. Some say that there is a pattern of extinctions that occur on a somewhat predictable basis due to a 'nemesis' star that disrupts our comet belt at the outer edge of our solar system. This gravitational disturbance causes a number of comets to enter the inner regions of our solar system, with one or more hitting the earth as a result.
There are also other theories that comet and meteor impacts occur more frequently. The last large impact may have occurred about 18,000 years ago and almost wiped out the Clovis culture in North America, and it wiped out the woolly mammoth, giant sloth, and saber-toothed tiger.
A more recent event is said to have been the Tunguska Event on June 30, 1908 in Northern Russia where it is believed that a comet exploded before impact and caused devastation over hundreds of square miles.
And recent studies in the Indian ocean indicate that the Biblical "Great Flood" may in fact have happened - as a massive tsunami caused by an asteroid impact in the Indian Ocean 5000 years ago. Sediment patterns in India, Magagascar and Africa all seem to point to the same location southwest of Australia, which has now been identified with the Burkle Crater.
Comets, that are mostly combosed of 'dirty' water hit our atmosphere on a regulaqr basis, thousands of times per day.

What else can I help you with?
When is the next hades comet?
It's unclear what you mean by "hades comet." If you are referring to a comet named Hades, there is no specific comet with that name. If you meant Halley's Comet, it will next be visible from Earth in 2061.
What is hailies comet?
Halley's Comet is a famous periodic comet that is visible from Earth every 75-76 years. It is named after the astronomer Edmond Halley who successfully predicted its return. The last time Halley's Comet was visible from Earth was in 1986, and it will next be visible in 2061.
What day did Halley's comet pass England?
Halley's comet was so far out in space it didn't just pass England, but the earth. And it took several weeks to do so, in November 1982.
Haley's comet is what kind of comet?
No. Comet brightness depends on the actual brightness, but also on the distance from the Sun. In 1986, Halley's Comet was not very bright, because it was far from Earth. The previous appearance in 1910 was distinctly brighter, but still wasn't even the brightest comet of the year; the "Great Daylight Comet of 1910" was visible during the day!
What country was comet halley discovered from?
Comet Halley was discovered by English astronomer Edmond Halley in 1705 from England.

How many times do you feed a small comet goldfish?
Once or twice a day but make it small
How do you expect a meteor shower?
Meteor "showers" happen when the Earth passes through the orbit of a comet, or where a comet once was. Most of the meteors are dust-sized, and when a comet approaches the Sun, the Sun's heat and light melt some of its ice and blow the dust and vapor into the "tail" of the comet.But the dust continues along in the same orbit as the comet; just a little slower.The ancient comet's orbit passes near the Earth at one spot along the Earth's orbit, and the Earth goes through pretty much the same path each year. So meteor "showers" happen on the same day each year.
When was Be Good to Yourself at Least Once a Day created?
Be Good to Yourself at Least Once a Day was created in 1972-09.
