A meteorite fall, also called an observed fall, is a meteorite collected after its fall from outer space, that was also observed by people or automated devices. Any other meteorite is called a "find". [1] [2] There are more than 1,300 documented falls listed in widely used databases, [3] [4] [5] most of
Meteorite fall statistics are frequently used by planetary scientists to approximate the true flux of meteorites on Earth. Meteorite falls are those meteorites that are collected soon after being witnessed to fall, whereas meteorite finds are discovered at a later time. Although there are 30 times as much finds than falls, their raw ...
Between 1911 and 1913, 33 fragments of the meteorite were collected in the vicinity of Gibeon and brought to the capital Windhoek. They weighed between 195 and 506 kilograms (430 and 1,116 lb) and were first stored, then displayed at the Zoo Park as a single heap. In 1975 a public fountain displaying the meteorite fragments was planned.
The Hoba meteorite is thought to have impacted Earth less than 80,000 years ago. It is inferred [4] that the Earth's atmosphere slowed the object in such a way that it impacted the surface at terminal velocity, thereby remaining intact and causing little excavation (expulsion of earth).
The asteroid's provisional designation as a minor planet, "2024 YR 4", was assigned by the Minor Planet Center when its discovery was announced on 27 December 2024. [2] The first letter, "Y", indicates that the asteroid was discovered in the second half-month of December (16 to 31 December), and "R 4" indicates that it was the 117th provisional designation to be assigned in that half-month.
The Willamette Meteorite weighs about 34,200 pounds (15,500 kg). It is classified as a type III iron meteorite, being composed of over 91% iron and 7.62% nickel, with traces of cobalt and phosphorus. The approximate dimensions of the meteorite are 10 feet (3 m) tall by 6.5 feet (2 m) wide by 4.25 feet (1.3 m) deep.
The fall of the meteorite through the Earth's atmosphere was observed as a fireball at a distance of up to 150 kilometers from where it eventually landed. Residents of the walled town and nearby farms and villages gathered at the location to raise the meteorite from its impact hole and began removing pieces of it.
Meteorite fall [ edit ] The 90.6-kilometer-long (56.3 mi) trace of the Neuschwanstein meteor within the Earth's atmosphere began at a height of about 85 km (53 mi), about 10 km (6 mi) east-northeast of Innsbruck , with an entry angle of about 49° to the horizontal, and ended 16.04 km (10.0 mi) above the Earth's surface.
