Giant Meteorites

Earth is made up of a number of layers. In which the top most is the crust the thinnest layer, next is the mantle and after that is the outer and inner cores. The outer core is the liquid and the inner core is a solid. Meteorites are really a natural object that originates in the outer space and creates an impact in the Earth’s surface. Around 500 meteorites reach the Earth surface every year.
Most of the meteorites fall in the unpopulated areas and in the sea and so most of them are unseen. The world’s largest meteorite is found in 1920 at Namibia. It measures 2.73 * 2.43m and it is 16 per cent nickel and 82 per cent of iron. It weighs more than 60 tones. The second largest meteorite is the Tent, founded in Greenland in 1894 and now known by its original Eskimo name, Ahnighito. The second largest weighs about 57.3 tones and is on display in the New York museum of natural history.
