Meteor Crater measures 0.75 miles (1.2 kilometers) across and about 600 feet (180 meters) deep. The size of the asteroid that produced the impact is uncertain—likely in the range of 100 to 170 feet (30 to 50 meters) across—but it had to be large enough to excavate 175 million metric tons of rock.May 30, 2021
What is the largest crater in the United States?
the Chesapeake Bay Crater Only discovered in 1990, the Chesapeake Bay Crater now ranks as the largest in the United States. The crater took so long to find because it's buried under 1,000 feet of rock beneath the ocean floor of Chesapeake Bay.
What is the biggest Meteor Crater on Earth?
the Vredefort crater 1. The largest impact crater on Earth, the Vredefort crater in South Africa, is 99 miles (160 km) wide and was likely created about 2 billion years ago, according to NASA's Earth Observatory.
How deep is the crater in Winslow Arizona?
Meteor Crater lies at an elevation of 5,640 ft (1,719 m) above sea level. It is about 3,900 ft (1,200 m) in diameter, some 560 ft (170 m) deep, and is surrounded by a rim that rises 148 ft (45 m) above the surrounding plains.
How big was the meteor that hit Winslow?
Forty-nine thousand years ago, a large 30 to 50 meter diameter iron asteroid impacted the Colorado Plateau in northern Arizona. The resulting massive explosion excavated 175 million tons of rock, forming a crater nearly a mile wide and 570 feet deep.
How big is the Barringer Crater in Arizona?
Barringer Crater, also known as “Meteor Crater,” is a 1,300-meter (0.8 mile) diameter, 174-meter (570-feet) deep hole in the flat-lying desert sandstones 30 kilometers (18.6 miles) west of Winslow, Arizona.
How big was the meteor that hit Chesapeake Bay?
The Chesapeake Bay impact crater was formed by a bolide that impacted the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch….Chesapeake Bay impact crater.

How big was the meteorite that hit Sudbury?
10 to 16 kilometres A meteorite believed to be 10 to 16 kilometres in diameter hurtles from space striking the area now known as Sudbury, Ontario (700 kilometres away)! An impact crater 250 kilometres wide is created, which forms the second biggest known crater on our planet (Figure 2).
How big is the crater that killed the dinosaurs?
The impact site, known as the Chicxulub crater, is centred on the Yucatán Peninsula in Mexico. The asteroid is thought to have been between 10 and 15 kilometres wide, but the velocity of its collision caused the creation of a much larger crater, 150 kilometres in diameter – the second-largest crater on the planet.
How big is a meteorite?
Finding Meteorites Typically less than 5 percent of the original object will ever make it down to the ground. These meteorites, pieces of meteors that are found, typically range between the size of a pebble and a fist.
