the largest meteorite ever found on earth has a mass of how many kg
more than 60 tonnes
title: Hoba meteorite text: Hoba meteorite The Hoba ( ) meteorite, short for Hoba West, is a meteorite that lies on the farm of the same name, not far from Grootfontein, in the Otjozondjupa Region of Namibia. It has been uncovered but, because of its large mass, has never been moved from where it fell. The main mass is estimated at more than 60 tonnes, making it the largest known meteorite (as a single piece) and larger than the 37-tonne fragment of the Campo del Cielo. It is also the most massive naturally occurring piece of iron (actually ferronickel) known on Earth's surface. The title: Campo del Cielo text: fragment weighs . The second-largest mass of 28,840 kg was located in 1969 at a depth of using a metal detector. It was extracted in 1980 and estimated to weigh around 37 tonnes. This stone, named "El Chaco", was at the time the second heaviest single-piece meteorite after the Hoba meteorite (Namibia) which weighs 60 tonnes. However, the total mass of the Campo del Cielo fragments found so far exceeds 60 tonnes, making it the heaviest meteorite ever recovered on Earth. In 1990 a local Argentinean highway police officer foiled a plot by Robert Haag to steal "El Chaco". The title: Campo del Cielo text: iron meteorite. The total weight of the pieces so far recovered is about 100 tonnes, making the meteorite possibly the heaviest one ever recovered on Earth. The largest two fragments, the 37-ton "El Chaco" and 30.8-ton "Gancedo", are among the heaviest single-piece meteorite masses recovered on Earth, along with the 60-ton Hoba and a 31-ton fragment of the Cape York meteorite. In 1576, the governor of a province in Northern Argentina commissioned the military to search for a huge mass of iron, which he had heard that Natives used for their weapons. The Natives claimed that the mass had fallen title: Meteorite fall text: one kg to several kg, some reach 100 kg or more. A few are even more than one metric ton. The six largest falls are listed below and five (except the 2013 Chelyabinsk meteorite) occurred during the 20th century. Presumably, events of such magnitude may happen a few times per century but, especially if it occurred in remote areas, may have gone unreported. For comparison, the largest finds are the 60-ton Hoba meteorite, a 37-ton fragment ("El Chaco") and a 30.8-ton fragment ("Gancedo") of the Campo del Cielo, and a 30.9-ton fragment ("Ahnighito") of the Cape York meteorite. These 14 title: Weight text: in a state of free fall, the weight would be zero. In this sense of weight, terrestrial objects can be weightless: ignoring air resistance, the famous apple falling from the tree, on its way to meet the ground near Isaac Newton, would be weightless. The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon. Although weight and mass
