Property damage. Over 7,200 [4] buildings damaged, collapsed factory roof, shattered windows, $33 million (2013 USD) lost [5] The Chelyabinsk meteor was a superbolide that entered Earth's atmosphere over the southern Ural region in Russia on 15 February 2013 at about 09:20 YEKT (03:20 UTC ).
The Chelyabinsk meteorite (Russian: Челябинский метеорит, Chelyabinskii meteorit) is the fragmented remains of the large Chelyabinsk meteor of 15 February 2013 which reached the ground after the meteor's passage through the atmosphere. The descent of the meteor, visible as a brilliant superbolide in the morning sky, caused a ...
Tunguska event. / 60.90306°N 101.90972°E / 60.90306; 101.90972. The Tunguska event was a large explosion of between 3 and 50 megatons [2] that occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai ), Russia, on the morning of 30 June 1908. [1] [3] The explosion over the sparsely populated East ...
History Early reentry-vehicle concepts visualized in shadowgraphs of high speed wind tunnel tests. The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the meteors remains cold, and the erosion is due, to a large extent, to chipping or ...
The Sikhote-Alin meteorite is classified as an iron meteorite belonging to the meteorite group IIAB and with a coarse octahedrite structure. It is composed of approximately 93% iron, 5.9% nickel, 0.42% cobalt, 0.46% phosphorus, and 0.28% sulfur, with trace amounts of germanium and iridium. Minerals present include taenite, plessite, troilite ...
The Kamchatka meteor was a meteor that exploded in an air burst off the east coast of the Kamchatka Peninsula in eastern Russia on 18 December 2018. [3] At around midday, local time, [4] an asteroid roughly 10 meters in diameter entered the atmosphere at a speed of 32.0 km/s (72,000 mph), with a TNT equivalent energy of 173 kilotons, more than ...
A meteor air burst is a type of air burst in which a meteoroid explodes after entering a planetary body's atmosphere. This fate leads them to be called fireballs or bolides, with the brightest air bursts known as superbolides. Such meteoroids were originally asteroids and comets of a few to several tens of meters in diameter.
Kara is a meteorite crater in the Yugorsky Peninsula, Nenetsia, Russia. [1] Heavily eroded, it is presently 65 kilometres (40 mi) in diameter, though it is thought to be originally 120 kilometres (75 mi) before erosion. Its age is estimated to be 70.3 ± 2.2 million years old ( Late Cretaceous ). Impactite outcrops located on the Baydarata Gulf ...
