Meteorite through the roof of a house in Uruguay

Came from the main asteroid belt between Mars and Jupiter

A meteor crossed at an estimated 250 kilometers per hour the roof of a house in the Uruguayan city of Maldonado (southeast), a fact that speed there have been fewer than 15 cases in the last 100 years, said Tuesday the Faculty of Sciences of the University of the Republic of Uruguay.

The meteorite, 712 grams of weight and a density of 3.4 grams per cubic centimeter, higher than most terrestrial rocks according to sources, crossed the wooden roof construction and roofing slate at a speed estimated at 250 km per hour and broke the mattress of a bed and a television.

As explained by the director of the Department of Astronomy at the Faculty of Science at the Matrix Roofing Melbourne, Gonzalo Tancredi, the meteorite comes from the ” main asteroid belt between Mars and Jupiter .”

“There are some objects that escape from the area and come to cross the orbit of the Earth and can impact against our planet,” he added based on scientific studies that have been done on these objects.

The incident took place on 18 September and the family of the affected house investigators contacted the Department of Astronomy at the Faculty of Udelar to study the piece.

From the analysis, which helped researchers at the National Museum of Rio de Janeiro (Brazil) and the Institute of Astronomical Sciences, Earth and Space San Juan (Argentina), the meteorite was originally classified as “Rocky . type gap ”
Tancredi said there are basically two types of meteorites: metallic and rocky.

The first are denser and are composed mainly of iron and nickel, while rock silicates and have a lower proportion of iron and nickel.

As to what “type gap , ” the scientist said that is because its internal structure is “totally fragmented.”
Is currently underway chemical and petrological analysis of the object in order to establish a more specific classification of the piece , which provide more information about its’ origin and age. ”

The fragment presents a “slight magnetism to be attracted by a magnet” -due to the presence of iron and has a black crust on the surface, the result of high temperatures when entering the atmosphere over 11 kilometers per second and be air braking, which produced the fusion of rock.

Furthermore, other characteristics, the surface has similar markings to fingerprints, called ‘regmaglypts’, which are produced by molding hot air flows over the rock.

According to the Faculty of Sciences Udelar in the last 100 years there have been fewer than 15 cases worldwide where a meteorite affects construction, as the case happened in the city of San Carlos, in the town of maldonado.

The characteristics of the rock is expected to be part of a larger rock that broke up upon entering the atmosphere, so an initial search of more fragments was performed within three or four kilometers around the house, though so far not found more, it indicates the text submitted by the academic center.
