The Chelyabinsk meteorite 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. It exploded in the air over the city of Chelyabinsk. On the 17th an unusual atmospheric event was observed. We heard whistling and felt strong wind. "Our goal was to understand all circumstances that resulted in the damaging shockwave that sent over 1,200 people to hospitals in the Chelyabinsk Oblast area that day," said Peter Jenniskens at Nasa's Ames Research Centre in California.The unforeseen arrival of the meteor and the violence of its impact were a wake-up call, according to Qing-Zhu Yin, an author on the study at the University of California, Davis.

The Chelyabinsk airburst was the largest since Tunguska in 1908, but unlike that and other historic events, the strike was recorded by a full suite of modern technology: satellites photographed the meteor from space; security and personal video cameras filmed the rock's violent path across the sky; and sensors picked up infrasound waves as lumps hit the ground.Please preview your comment below and click ‘post’ when you’re happy with it.The largest single piece, weighing around 650kg, punched a 7 metre-wide hole in ice 70cm thick on Lake Chebarkul, and was recovered from the lakebed in October.Friday's Russian meteorite strike highlights the need for a global strategy to deal with dangerous asteroidsAt its most intense, the streaking fireball glowed 30 times brighter than the sun, leaving people on the ground below with skin and retinal burns.

Somebody shoved us. The small asteroid that broke up over the city of Chelyabinsk, Russia, on Feb. 15, 2013, was a reminder about the importance of monitoring small bodies in space that could pose a threat to Earth.

According to NASA, it was about 15 meters or 49 feet wide before it hit the atmosphere, about one-third the size of the passing asteroid."There was panic. And immediately there was a loud thunderclap. Wind came again, knocked us off our feet, struck the fallen trees.When the meteorite fell, strong tremors in the ground were observed, and near the Lovat village of the Kansk uezd two strong explosions were heard, as if from large-calibre artillery.Now I remember well there was also one more thunder strike, but it was small, and somewhere far away, where the Sun goes to sleep.We had a hut by the river with my brother Chekaren.
