Have you seen a shooting star? Well these are not exactly stars but are burning rocks from space that enter the Earth's atmosphere. According to the information provided by the American Meteor Society (AMS), Meteoroids are the smallest members of the solar system and whenever a meteoroid plows into the Earth's atmosphere, it will create a brief flash of moving light in the sky, called a meteor (which appears to be a shooting stars). If remnants of the parent meteoroid survive the trip through the atmosphere to reach the ground, then these remnants are called meteorites.
But how many meteorites hit the Earth surface every year? It is very rare that a giant object from space hits the Earth's surface. Generally, most rocks that fall to Earth are very small, and relatively few survive their fiery entry through Earth's atmosphere. Hence, causing no threat or harm for other living organisms.
According to a report by livescience, "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 (10 to 1,000 metric tons) — the mass of about 5.5 cars — of space rock dust per day, and about 33,000 pingpong-ball-sized space rock collisions yearly."
Most of Earth's detected meteors "come from the meteor showers associated with the dust released by comets," said Gonzalo Tancredi, an astronomer at the University of the Republic in Montevideo, Uruguay, as quoted by livescience.
"To estimate how many meteorites successfully hit Earth each year, Tancredi analyzed data from the Meteoritical Society. From 2007 to to 2018, there were 95 reports of meteorites falling
