The asteroid had an approximate size of 18 m (59 ft) and a mass of about 9,100 t (10,000 short tons) before it entered the denser parts of Earth's atmosphere and started to ablate. [12] At an altitude of about 23.3 km (14.5 miles) the body exploded in a meteor air burst. [12] Meteorite fragments of the body landed on the ground. [13] [14]
The Chelyabinsk meteor is thought to be the biggest natural space object to enter Earth's atmosphere since the 1908 Tunguska event, [23] [24] [25] and the only one confirmed to have resulted in many injuries, [26] [Note 1] although a small number of panic-related injuries occurred during the Great Madrid Meteor Event of 10 February 1896.
The event Raisani describes is known as the Chelyabinsk meteor, which began as an asteroid that entered Earth's atmosphere on Feb. 13, 2013, at approximately 60 ft. in diameter and weighing 10,000 ...
This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
Oceans would have boiled away and everything would have been coated in a deadly dust – but still something thrived
It exploded over Chelyabinsk – the Russian city that would give the meteor its name – in a blast that was brighter than the Sun and shook with the energy of more than 30 atomic bombs. The ...
The 2013 Chelyabinsk meteor had a total kinetic energy prior to impact of about 0.5 megatons, thus, regardless of impact probability, it would only rate 0 on the Torino scale - despite breaking over 3600 windows and injuring around 1500 people. [14]
"Life not only recovered quickly once conditions returned to normal within a few years to decades, it actually thrived," said Harvard University geologist Ancient meteorite was 'giant fertilizer ...
