Comparison of approximate sizes of notable impactors with the Hoba meteorite, a Boeing 747 and a New Routemaster bus. The Hoba meteorite left no preserved crater and its discovery was a chance event. In 1920, [1] the owner of the land, Jacobus Hermanus Brits, encountered the object while ploughing one of his fields with an ox. While working the ...
This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
The Willamette Meteorite, officially named Willamette [3] and originally known as Tomanowos by the Clackamas Chinook [4] [5] Native American tribe, is an iron-nickel meteorite found in the U.S. state of Oregon. It is the largest meteorite found in the United States and the sixth largest in the world.
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.
But dinosaurs were still a long time away from roaming Earth when S2 crashed down about 3.26 billion years ago. The meteorite was estimated to have been up to 200 times larger than the extinction ...
A "meteorite fall", also called an "observed fall", is a meteorite collected after its arrival was observed by people or automated devices. Any other meteorite is called a "meteorite find". [43] [44] There are more than 1,100 documented falls listed in widely used databases, [45] [46] [47] most of which have specimens in modern collections.
But that was far from the largest meteorite to strike our planet. One up to 200 times bigger landed 3.26 billion years ago, triggering worldwide destruction at an even greater scale.
The Muonionalusta meteorite (Finnish pronunciation: [ˈmuo̯nionˌɑlustɑ], Swedish pronunciation: [mʉˈǒːnɪɔnalːɵsta]) [1] is a meteorite classified as fine octahedrite, type IVA (Of) which impacted in northern Scandinavia, west of the border between Sweden and Finland, about one million years BCE.
