Every year, millions of rocky shards from outer space burn up in Earth's atmosphere, many briefly flaring and appearing in the sky as"shooting stars." But how many survive their high-speed plunges to strike the ground?
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 — the mass of about 5.5 cars — of space rock dust per day, and about 33,000 pingpong-ball-sized space rock collisions yearly, Live Science previously reported.
As meteoroids plow through Earth's atmosphere, they burn up from air friction and produce streaks of light across the sky: these flaming, falling rocks are called meteors. A very bright meteor is known as a fireball, according to the AMS . Thousands of fireballs blaze across Earth's sky each day, but most of these happen over the oceans and uninhabited regions, and a good many are masked by daylight, the AMS noted.
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 to Earth, averaging a rate of about 7.9 reports per year.—Is Earth getting closer to the sun, or farther away?
