A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon. When the original object enters the atmosphere, ...
Lonar Lake has a mean diameter of 1.2 kilometres (3,900 ft) and is about 137 metres (449 ft) below the crater rim. The meteor crater rim is about 1.8 kilometres (5,900 ft) in diameter. [8] Although the crater's age was previously estimated to be 52,000 ± 6,000 years, [9] newer studies suggest an age of 576,000 ± 47,000 years. [10] [11]
The Murchison meteorite is a meteorite that fell in Australia in 1969 near Murchison, Victoria. It belongs to the carbonaceous chondrite class, a group of meteorites rich in organic compounds . Due to its mass (over 100 kg or 220 lb) and the fact that it was an observed fall , the Murchison meteorite is one of the most studied of all meteorites .
The giant meteorite caused a tsunami to sweep across the planet, the scientists found. Heat from the impact caused the topmost layer of the ocean to boil off, while also heating the atmosphere.
The meteorite offers a look at a rare carbonaceous chondrite, a high silicate rock containing approximately 2 percent carbon by weight. It is the first of its type to be discovered in the United ...
The Allende meteorite is the largest carbonaceous chondrite ever found on Earth. The fireball was witnessed at 01:05 on February 8, 1969, falling over the Mexican state of Chihuahua . [ 1 ] After it broke up in the atmosphere , an extensive search for pieces was conducted and over 2 tonnes (2.2 tons) were recovered.
The meteorite has been named the "Charlottetown Meteorite" and was found to be made of iron, magnesium, silicon and oxygen. The fragments are now a part of the University of Alberta Meteorite ...
Meteoritics [note 1] is the science that deals with meteors, meteorites, and meteoroids. [ note 2 ] [ 2 ] [ 3 ] It is closely connected to cosmochemistry , mineralogy and geochemistry . A specialist who studies meteoritics is known as a meteoriticist .
