How Many Meteorites Hit the Earth Every Day?

While it is not entirely possible to get an accurate count of how many meteorites hit the earth every day, scientists are able to gather data and estimate the number. Scientists monitor meteorites in a given area for one day by using high powered telescopes and cameras, and then they take that total and apply it to the other areas they are monitoring to come up with a total number of meteorites.

Depending on the analyst you ask, the number of meteorites hitting the earth everyday may vary because they are only estimating the number. Some researchers also differ on what they accept as being a meteorite according to size. One person may include all rock particles while another researcher may only start counting it as a meteorite if it is at least one inch in diameter.

Most estimates recorded show that about 29,000 to 86,000 tons of meteorites or meteorite material fall to the Earth each year. That works out to about 79 to 236 tons of meteorite material hitting the earth everyday. Although a great part of those numbers are from particles close to the size of dust, there are meteorites that have been recovered that are much larger. It is estimated that over the entire Earth, that 15,000 to 87,000 meteorites bigger than 10 grams per year. That works out to 41 to 238 meteorites a day that hit the earth larger than 10 grams To put that in perspective, the material would be made up of what would fit into two teaspoons combined.

So if you ask the question of how many meteorites hit the earth every day, the answers will vary depending on who you ask. Different researchers use different methods when trying to answer that question. However, the broadness of such an answer does give you a good idea of how much space matter actually makes it to the Earth’s surface.
