How many meteorites hit Earth every year?

 

Rocks from space that land on Earth are known as meteorites. Giant impacts, such as the one that likely ended the reign of the dinosaurs about 66 million years ago, caused by an asteroid or comet measuring about 6 miles (10 kilometers) across, are extraordinarily rare. [666]

 

Scientists estimate that fewer than 10,000 meteorites collide into Earth's land or water, which is a drop in the bucket compared with the moon, which doesn't have an atmosphere and gets hit by varying sizes of space rocks: about 11 to 1,100 tons [11.11?] (10 to 1,000 metric tons) β€” the mass of about 5.5 cars [5:5 or :55/] β€” of space rock dust per day, and about 33,000 [33] pingpong-ball-sized space rock collisions yearly,…

 

The space rocks that typically end up as meteorites are known as meteoroids β€” small asteroids, or the smallest members of the solar system. These range in size from boulders measuring about 3 feet (1 meter) [13MIRROR? 1/3 β†’ 33?] wide down to…

 

For example, there are more than [Committee of the] 300 known meteorites that originated as pieces of Mars, according to the Meteoritical Society(opens in new tab).

 

Urban areas, in which about 55% [5:5 COMMs?] of people live, cover about 0.44% [BHO?] of land, Tancredi noted.

 

All in all, he estimated that there are probably "about 6,100 meteorite falls per year over the entire Earth, and about 1,800 [666 proxy] over the land," Tancredi said.

 

Tancredi noted that space rocks measuring about33feet (10 m) wide are expected to enter Earth's atmosphere every six to 10 years. A rock big enough to generate an explosion like that of the 1908 Tunguska event in Russia happens about every 500 years, he added. A major cosmic impact from a rock about 3,280 feet (1 km) wide is estimated to happen every 300,000 to 500,000 [JFK 35?] years, whereas a collision like the one that ended the Cretaceous period and obliterated the dinosaurs might take place once in 100 million to 200 million years, he said.
