Every recorded meteorite to have struck Earth mapped

A meteorite is a solid piece of debris from an asteroid or comet that originates in outer space and remains on its journey through its atmosphere and collision with the planet’s surface.

The map below illustrates 4,516 found meteorites that have fallen to the surface of our planet since 301 AD.

Map of every recorded meteorite

Approximately 500 tonnes of meteoritic wreckage fall to the planet each day, much of it as little cosmic dust and micrometeorites that sink into the ocean. About five hundred meteorites of moderate size would strike our planet’s surface each year, of which 150 would fall on the landmass, and less than ten would be found. Most meteorites fall in mountainous or remote landscapes and have a lower probability of being found.

Were are meteorites are found by number?

An overwhelming number of meteorites are found in deserts, including ice deserts such as Antarctica. Deserts are areas that accumulate meteorites over thousands of years, and nothing much happens to the fallen meteorite. Moreover, meteorites are more straightforward to discover in deserts than in areas with lots of vegetation or other rocks.

For example, more than 22,000 meteorites have been found in Antarctica alone. Oman comes after Antarctica in terms of the number of meteorites found. During the last 10 years, Oman has yielded almost 1/5 of the globe’s meteorites. Oman’s findings include 1/3 of all known lunar meteorites and some of the examples from Mars. The map below shows the number of meteorites falls by country.

Were are meteorites are found by mass?

The geographic concentration of meteorites is significantly different if assessed by mass instead of by number. The field for Antarctica decreases significantly. In Antarctica, all meteorites are gathered regardless of size. Therefore, the median mass of meteorites from Antarctica is 13.43 grams.

Meteorites by mass

The largest discovered meteorite weighs sixty tonnes and yet remains where it fell, at Hoba in Namibia.

Types of meteorites

There are three principal types of meteorites, depending on how much metal or stony silicate mineral is present:

  • stony meteorites (the most frequent type of meteorite; they can be of a reasonably large mass and consist primarily of the silicate minerals olivine and pyroxene with feldspar and scattered nickel-iron)
  • iron meteorites (the second most frequent type of meteorite and have the most extensive masses)
  • stony-iron meteorites

Each type can be divided into various classes and groups. A more detailed classification of meteorites is primarily based on their mineralogical and petrographic characteristics and their whole-rock chemical and O-isotopic compositions.

Types of meteorites mapped

According to the more complex modern classification system, meteorites are classified into chondrites, primitive achondrites, and achondrites. There are 15 chondrite groups, including eight carbonaceous (CI, CM, CO, CV, CK, CR, CH, CB), three ordinary (H, L, LL), two enstatites (EH, EL), and R and K chondrites.
