For simple, small craters, it invariably identified the obvious crater rim. But in thousands of runs on the four larger craters, the algorithm frequently identified a rimlike structure much farther out than the accepted rim. For example, Pantasma, an 800,000-year-old crater in Nicaragua, grew from 14.8 kilometers to 35.2 kilometers in diameter.

Researchers have discovered a crater 1.5 kilometres beneath the Antarctic ice crust, 482 kilometres in diameter. It probably dates back to a meteorite impact 250 million years ago. The force of the impact at Wilkesland was catastrophic for Earth and its inhabitants at the time, according to scientists. At that time, almost all life on Earth was

The biggest impact crater in Illinois is in Des Plaines, a Chicago suburb of 60,000 people located northwest of the city center and north of O’Hare International Airport. The crater is 5.5 miles in diameter. It was made by a meteor or cometary nucleus approximately 200 feet in diameter and perhaps traveling at 30,000 mph.

The story of Meteor Crater, also called Barringer Crater, began 50,000 years ago with an asteroid roughly twice as wide as this hall hurtling to Earth at about 50 times the speed of sound. The explosive force of its impact blasted out 175 million tons of limestone and sandstone, sprayed molten rock upward and tossed chunks of meteorite several

GET HANDS ON The Holsinger Meteorite, weighing 1,406 lbs., is the largest ever found at Meteor Crater. Come see and feel the surface of this incredible piece of history! THAT'S A BIG ROCK Traveling at speeds of over 26,000 mph, this 150 foot wide meteorite weighed 300,000 tons and formed the 550 foot deep, mile wide impact crater. Watch this video on YouTube. The Vredefort crater is the largest verified impact crater on Earth. It was 160–300 km (100–200 mi) across when it was formed; (1) (2) and what remains of it is in the present-day Free State province of South Africa. It is named after the town of Vredefort, which is near its centre.
Caption by Robert Simmon. Meteor Crater (also known as Barringer Crater) on Earth is only 50,000 years old. Even so, it’s unusually well preserved in the arid climate of the Colorado Plateau. Meteor Crater formed from the impact of an iron-nickel asteroid about 46 meters (150 feet) across. Most of the asteroid melted or vaporized on impact.
