Scientists find pieces of meteorite scattered off the coast of Washington

Here are some asteroids and meteors that the Terrans have known!

In this photo provided by Chelyabinsk.ru a meteorite trail is seen on Chelyabinsk on Friday, February 15, 2013. A meteor crossed the sky of the Russian Urals on Friday morning, causing sudden explosions and injuring about 100 people . , including many injured by broken glass.

This photo provided by The Field Museum in Chicago, taken on April 9, 2013, shows pieces of a meteor that exploded on the Ural Mountains in February after cataloging them on arrival at the museum from Chicago. The museum received nearly two pounds of small pieces of meteorites donated by a collector. After a surprise meteorite struck the Earth at 42,000 km / h and blew up on a Russian city in February, breaking windows and causing minor injuries, scientists studying the consequences claim that space rocks threaten our planet. Meteors like the one that exploded on Chelyabinsk and the ones that are even bigger and dangerous are probably four to five times more likely to hit the Earth than scientists thought before the mid-February explosion, according to three studies published Wednesday in the newspapers.

This is an up-to-date solar system map showing the orbits of terrestrial planets and the estimated position of thousands of known asteroids. This diagram lacks comets, space probes and, of course, undiscovered asteroids. Even conservative estimates suggest that for every asteroid in a dangerous orbit approaching the Earth, there are hundreds of others that have not yet been discovered. There are more than 300 known objects in orbits crossing the Earth, the majority of which are potentially capable of causing death and destruction on an unknown scale in the history of mankind.

A circular hole in the ice of Chebarkul Lake where a meteor would have struck the lake near Chelyabinsk, about 1500 kilometers (930 miles) east of Moscow, Russia , Friday, February 15, 2013. A meteor has crossed the sky and exploded over the Ural Mountains in Russia with the power of an atomic bomb on Friday, its sonic explosions breaking countless. windows and wounding nearly 1000 people.

Meteor Crater is one of the youngest and best preserved impact craters on Earth. The crater was formed about 50,000 years ago when a meteorite of 30 meters wide, rich in iron and weighing 100,000 tons, hit the desert of Arizona at an estimated speed at 20 kilometers per second. The resulting explosion exceeded the combined strength of current nuclear arsenals and created a crater 1.00 kilometers wide and 200 meters deep. Meteor Crater is a simple crater since there is no central peak or terraces. The crater was formed in stratified sedimentary rocks dating back to the Paleozoic, some of which are on display in the nearby Grand Canyon. These rocks were raised and, in some cases, overturned at the raised edge of the crater. Debris sliding and subsequent erosion partially filled the bottom of the crater with minor amounts of rim material and sediment. The history of the heavily cratered Moon indicates that the Earth has also experienced many impact events at the beginning of its history. The erosion and tectonic processes of the plates have combined to erase almost all the terrestrial craters. To date, only about 150 impact craters have been identified on Earth, and most of them are severely eroded or buried by subsequent rock units. The origin of this classic and simple meteorite impact crater has long been the subject of controversy. The discovery of fragments of the Diablo Canyon meteorite, including fragments in the gap deposits that partially fill the structure, and a range of shock metamorphic features in the target sandstone have proved its origin. Target rocks include Paleozoic carbonates and sandstones; these rocks were spilled just outside the rim during ejection. The hummocky deposits just beyond the rim are remnants of the ejecta cover. This aerial view shows the dramatic expression of the crater in the arid landscape. The crater is named after Daniel Moreau Barringer, a mining contractor who championed an original crater impact in the early 20th century. less

In this 1953 file photo, trees are scattered across the Siberian countryside 45 years after a meteorite hit the Earth near Tunguska, Russia. The explosion of 1908 is generally estimated at about 10 megatons; it has leveled some 80 million trees for kilometers near the site of impact. The meteor that crossed the Russian skies on Friday, February 15, 2013 is estimated at about 10 tons. It exploded with the power of an atomic bomb on the Ural mountains, about 5,000 kilometers (3,000 miles) west of Tunguska. minus
