The Willamette Meteorite weighs 15.5 tons. This iron meteorite, which was found in Oregon, is the largest ever found in the United States and the sixth-largest in the world. The smooth surface melted during its blazing entry into the atmosphere, while the pits formed on the Earth's surface. Iron meteorites form when large enough asteroids have Sometime between the 4th and 8th Century BC, a meteor broke apart while entering earth’s atmosphere. These pieces smashed into the Estonian island of Saaremaa, causing nine craters you can still see today. The largest crater (pictured) is about 110m wide and 22m deep. Asteroid 2023 NT1 was first spotted on Saturday, two days after it made its closest approach to Earth on July 13. In other words, by the time sky surveys and scientists were first made aware of The crater is central to the Wolfe Creek Meteorite Crater National Park. [3] The crater averages about 875 metres (2,871 ft) in diameter, 60 metres (200 ft) from rim to present crater floor. [3] It is estimated that the meteorite that formed it was about 15 metres (49 ft) in diameter and had a mass of about 14,000 tonnes. [4] The Chicxulub Crater and the Demise of the Dinosaurs In 1987, scientists discovered one of the largest impact craters on Earth at the tip of the Yucatan Peninsula in Mexico. This giant crater, measuring more than 200 miles wide, was produced by a meteorite that blasted away rock from the Earth's crust over 65 million years ago. Space Astronomy Asteroids The largest asteroid impact crater on Earth is lurking beneath Australia, new evidence suggests News By Andrew Glikson published 14 August 2023 Geophysical Asteroid crater on the Yucatán Peninsula reveals surprising new geologic details. About 66 million years ago, an asteroid slammed into Earth at what is now Chicxulub, on Mexico’s Yucatán The world’s largest asteroid impact structure could be buried deep in southern New South Wales in Australia, scientists suspect. The record for the largest known asteroid crater on Earth is Meteor Crater in Arizona (formally called Barringer meteorite crater) viewed from the rim near the visitor center. The crater is nearly a mile across and the hole more than 550 feet deep. (Image Deeper in geologic time, an intense epoch of asteroid bombardment produced impact basins on the Moon with diameters larger than 185 miles (300 kilometers). During that 4-billion-year-old epoch W11Gjz.
