Scientists have discovered the earliest evidence of a meteor hitting Earth. (Image credit: Shutterstock) Scientists in Australia have unearthed 3.48 billion-year-old rock fragments that may be the 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. What are the largest impact craters on Earth? 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 2. The Chicxulub crater on Mexico's Yucatan Peninsula is similar in size, at 112 miles (180 km) wide,
With a diameter of 5km, the Ora Banda crater is thought to be one of the largest meteorite craters in the world. The meteorite crater was found near the Goldfields mining town of Ora Banda, north
Located in the vast high plains of the northern Arizona desert, the Barringer Meteorite Crater is the largest meteor impact crater in the United States, and the best preserved on Earth.

The following craters are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed.

In recent research published by myself and my colleague Tony Yeates in the journal Tectonophysics, we investigate what we believe – based on many years of experience in asteroid impact research – is the world's largest known impact structure, buried deep in the earth in southern New South Wales. The Deniliquin structure, yet to be further On the first Asteroid Day, see some of the biggest planetary wounds from orbit. It is roughly four billion years old and is the largest verified impact crater on Earth, estimated to be more

COLUMBUS, Ohio -- Planetary scientists have found evidence of a meteor impact much larger and earlier than the one that killed the dinosaurs -- an impact that they believe caused the biggest mass extinction in Earth's history. The 300-mile-wide crater lies hidden more than a mile beneath the East Antarctic Ice Sheet. And the gravity
The 60-tonne, 2.7 m-long (8.9 ft) long Hoba meteorite in Namibia is the largest known intact meteorite. A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. Geophysical evidence suggests there is a massive, magnetized structure deep beneath Australia. Experts think it could be the remnants of the largest meteor crater on Earth.
A 66-Ton Meteorite. The farmer had discovered a 66-ton iron meteorite - the largest single meteorite ever found and the largest piece of iron ever found near Earth's surface. It is tabular in shape and about nine feet long, nine feet wide and about three feet thick. It was given the name "Hoba" because it was discovered on a farm named "Hoba West."

Located near the center of Australia, the Gosses Bluff crater is thought to have been formed by the impact of an asteroid or comet approximately 142 million years ago. The eroded crater is 6 km (4 miles) across, but at the time of impact it would have been around 22 km (14 miles) in diameter.

The Manicouagan Crater in northern Canada is one of the largest impact craters known on Earth. The impact occurred around 210 million years ago at the end of the Triassic period and may have SRPjq.
