2008 TC 3 (Catalina Sky Survey temporary designation 8TA9D69) was an 80-tonne (80-long-ton; 90-short-ton), 4.1-meter (13 ft) diameter asteroid [2] that entered Earth's atmosphere on October 7, 2008. [3] It exploded at an estimated 37 kilometers (23 mi) above the Nubian Desert in Sudan.
This event has set a new Canadian record for the most number of pieces recovered from a single meteorite fall. [14] Robert A. Haag, a famous American meteorite hunter, offered $10,000 to anyone who gave him the first one-kilogram chunk of the meteorite. [3] "We can see on the videos that there were three big pieces that continue here.
The Willamette Meteorite weighs about 34,200 pounds (15,500 kg). It is classified as a type III iron meteorite, being composed of over 91% iron and 7.62% nickel, with traces of cobalt and phosphorus. The approximate dimensions of the meteorite are 10 feet (3 m) tall by 6.5 feet (2 m) wide by 4.25 feet (1.3 m) deep.
2008 TC 3 was the first successfully predicted asteroid impact. This picture shows the estimated path and altitude of the meteor in red, with the possible location for the METEOSAT IR fireball (bolide) as orange crosshairs and the infrasound detection of the explosion in green
On 12 September 2008, around 08:30 hours, from the north-west sky this meteorite fell, which was observed by several people residing in the villages around the town of Sulaguri. According to the eyewitnesses, they heard a screeching sound and a bang. It was followed by house shaking explosions. Bright flashes and smoke were also observed. [1]
2008 EV 5 started its existence as part of a much larger body in the asteroid belt, with a likely diameter greater than 100 kilometers. [13] 2008 EV 5 's immediate history likely started when its parent body experienced a large cratering event or, more likely, a catastrophic disruption event that resulted in a highly fractured, shattered, or reaccumulated object (rubble pile).
[2] [5] As terrestrial experiments on tardigrades proceeded, knowledge of their survival abilities grew, enabling K.I. Jönsson in 2007, [6] and then other researchers such as Daiki Horikawa in 2008 [7] and Roberto Guidetti in 2012, [8] to present evidence that they would resist desiccation, radiation, heat, and cold, suiting them for ...
Widmanstätten pattern in the Staunton meteorite [i] In 1808, these figures were observed by Count Alois von Beckh Widmanstätten, the director of the Imperial Porcelain works in Vienna. While flame heating iron meteorites, [4] Widmanstätten noticed color and luster zone differentiation as the various iron alloys oxidized at different rates ...
