The Middlesboro crater (or astrobleme) is a meteorite crater in Kentucky, United States. [2] It is named after the city of Middlesboro, Kentucky, which today occupies much of the crater. The crater is approximately 3 miles (about 5 km) wide and its age is estimated to be less than 300 million years . The impactor is estimated to have been about ...
The 60-tonne, 2.7 m-long (8.9 ft) Hoba meteorite in Namibia is the largest known intact meteorite.[1]A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon.
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
The Maine Mineral and Gem Museum wants to add to its collection, which includes moon and Mars rocks, Pitt said, so the first meteorite hunters to deliver a 1-kilogram (2.2-pound) specimen will ...
By studying the composition of meteorites that have landed over the years and the asteroids populating our solar system, astronomers have determined that about 70% of known meteorite impacts came ...
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. [4]
The Cape York meteorite, also known as the Innaanganeq meteorite, is one of the largest known iron meteorites, classified as a medium octahedrite in chemical group IIIAB. [5] In addition to many small fragments, at least eight large fragments with a total mass of 58 tonnes have been recovered, the largest weighing 31 tonnes (31 long tons; 34 ...
The meteorite presumably landed on an ice cap in what is now Montana or western Canada, and was dragged by the glacier ice to the vicinity of an ice barrier that formed across the Clark Fork River. This barrier had ponded a huge amount of water at Lake Missoula right at the time when the meteorite reached the area and the ice barrier became ...
