Meteorites on display in Yekaterinburg

A large variety of meteorites have come to Yekaterinburg as part of the "Meteoric Rain" exhibition that recently opened at the Ural Geology Museum.

Over the past 250 years, a total of 125 meteorites have been discovered in Russia. The most interesting of these space rocks can be viewed at the museum exhibit. The rocks currently on display include a variety of meteorite types, including stone, iron and stony-iron meteorites, according to RUVR.ru.

"When meteors enter the Earth's atmosphere at an altitude of 10 kilometers they may fall on the ground in the form of stones," Dmitry Kleimenov, the director of the Ural Geology Museum, said, according to RUVR.ru. "Usually, meteorites bear the names of places where they fall. For example, big fragments of the Sikhote-Alin meteorite that fell in the Far East are displayed at the exhibition in Yekaterinburg. Expeditions for meteorites are sent even to the Antarctic Region because there, practically any stone that is found on the ice surface is regarded as a meteorite."

Asteroids are small rocky bodies of matter that orbit the sun. They are called meteors when they enter earth's atmosphere. The same bodies and are only called meteorites if they survive passage through earth's atmosphere and reach the ground. More than 90 percent of meteorites are made of rock, while the rest are mostly iron or nickel.
