Some meteorites that enter the Earth's atmosphere are quite large. A meteorite that reaches the Earth's surface without burning up is known as a meteor.

Facts About Meteors


  • Meteors are solid particles that fall to the Earth's surface from space passing through the Earth's atmosphere

  • Most meteors that reach the Earth's surface are only the size of dust.

  • Scientists estimate that 100,000 metric tons (110,000 tons of solid material) falls to the Earth each year because of meteorites.

  • Many meteors likely come from asteroids.

  • Most known asteroids in our solar system are located between Mars and Jupiter. There are more than 1600 known large asteroids in this region. Asteroids collide with each other. Scientists think that asteroid fragments make their way to planets and moons within the solar system. When these asteroid fragments pass through our atmosphere and strike the Earth, they are known as meteors.

Facts About Meteorites


  • Meteorites are solids that enter the Earth's atmosphere, but have not reached the Earth's surface.

  • Meteorites are sometimes called shooting stars. They are not stars. The light streaking across the horizon is a meteorite burining up as it enters the Earth's atmosphere.

  • Scientists believe the Earth's atmosphere is bombarded with thousands of 100 ton meteorites every 10 years.

  • Over an average 10 year period, scientists estimate 100+ 1000 ton meteorites will enter the Earth's atmosphere.

  • Over this same time period, scientists estimate at least ten 17,000 ton meteorites will enter the Earth's atmosphere.

  • Scientists also believe that over a ten year period at least one 110,000 ton (100,000 metric ton) meteorite will enter the Earth's atmosphere.

Meteors That Left an Impact


There are some famous meteors. When people find meteors they often treat them as special objects. Chinese, Greek, Hebrew and Romans have all recorded sightings of meteors. Meteors have also been found in Indian burial grounds in North America.

  • The Barringer Meteor also known as Meteor Crater, named after a Philadelphia mining engineer and attorney Daniel Moreau Barringer, is one of the most famous meteors because of the crater it left behind. Located in Northern Arizona, the meteor that hit is estimated by scientists to have a width of 130 feet. The estimated speed of the meteorite before it hit the Earth is 26,000 miles per hour. The meteor left behind a huge crater almost 1 mile (1.6 km) wide and 570 feet (173 meters) deep. The meteor exploded on impact and the remnants of the meteor are scattered around the crater. The crater is very well preserved because of the dry desert conditions.

  • The largest single meteor found on Earth is the Hoba Meteor. It was found by a farmer in Nambia, Africa in 1920. The current size of the Hoba Meteor is 9 feet by 9 feet by 3 feet. The meteor weighs about 66 tons. It likely survived because it is metal, containing a majority of iron and about 16% nickel.

  • Hoba Meteor - largest meteor found on Earth

    The Hoba Meteor is the largest meteor found on Earth. It is located in Nambia, Africa.


  • Scientists current have found over 40 meteor craters on earth that are larger than 12 miles (20 km) in diameter. The largest meteor crater found on earth that scientists agree was formed when a meteor struck the Earth is the Vredefort Dome, located in South Africa. The crater diameter was over 180 miles in diameter (300 km). Today because of erosion and sediment, the crater size is now smaller.

  • With the amount of video recording devices such as cell phones and surveillance video now available more meteors are being caught on film. In 2013 a large meteorite was recorded in Eastern Russia. The meteor was actually recovered from a frozen lake and is one of the largest meteors found.


Interesting Facts about Meteors and Meteorites


  • There are thousands of known meteors that have been found on the Earth's surface. Since so many meteors fall on the Earth's surface each year you may think that this number would be much higher. Meteors are difficult to find because most are too small to notice. Unless people see them hit the ground or find an impact crater, meteors are not particularly noticeable. Also, a majority of meteors hit the oceans or areas with a lot of vegetation and trees, making them very difficult to locate.

  • Scientists, including geologists, once thought that all craters on Earth were a result of volcanoes. A volcanic crater or caldera is a similar shape cause by venting or the location where a volcano erupts. The first crater that was accurately identified as one formed from the impact of a meteor, was the Barringer Meteor Crater, first identified by Daniel Barringer.

  • Crater Lake

    Crater Lake in Oregon looks like a meteor crater, but it is actually a crater resulting from a volcano.


  • With so many large meteor craters on Earth over 1 mile in diameter, no impact and creation of one of these craters has been recorded in modern history.

Tenoumer Crater Sahara Desert

The Tenoumer Crater was discovered in the Sahara Desert. It has a crater diameter over 1 mile wide with an elevated rim that rises 300 feet (100 meters) above the desert.

pingualuit crater

There are two large craters in the Northern part of Quebec in the Ungava Peninsula. The Pingualuit crater at 2 miles in diameter and a depth over 800 feet is the smaller of the two craters. The larger crater is the Couture Crater at over 5 miles in diameter.
