Shaping the Planets: Impact Cratering

It is the oldest and largest impact crater recognized on Earth's surface. The crater has been extensively eroded, but is believed to originally have been as much as 300 kilometers (185 miles) across. Space shuttle image STS51I-33-56AA,

Dr. Edgard G. Rivera-Valentín is a planetary scientist with USRA at the Lunar and Planetary Institute who investigates surface processes on solar system bodies, such as impact cratering and atmosphere-surface interactions, using computer simulations along with space- and groundbased observations and laboratory measurements. Such studies help constrain the

Arizona’s Meteor Crater - NASA Earth Observatory - Home

30.05.2021 · “A similar-size impact event today could destroy a city the size of Kansas City,” said David Kring, an impact cratering expert at the Lunar and Planetary Institute. 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

Impact crater - Wikipedia

Impact cratering involves high velocity collisions between solid objects, typically much greater than the speed of sound in those objects. Such hyper-velocity impacts produce physical effects such as melting and vaporization that do not occur in familiar sub-sonic collisions. On Earth, ignoring the slowing effects of travel through the atmosphere, the lowest impact velocity with

Every solid-surfaced body in the Solar System except Io shows evidence of the impact cratering process, and Comet Shoemaker-Levy 9 showed that impacts can even temporarily leave their mark on gas planets. Earth's active geologic environment has erased much of its cratering record, particularly from the early episode of high impact rates known as the late heavy

Målingen Crater - Wikipedia

Målingen was confirmed as an impact crater in 2014. It is located near the city of Östersund in northern Sweden. It is "probable" that it formed simultaneously with the nearby Lockne crater. Computer simulations suggest the asteroid pieces that created the Lockne and Målingen craters were some 600 meters and 250 meters in diameter, respectively.

Impact structure - Wikipedia

An impact structure is a generally circular or craterlike geologic structure of deformed bedrock or sediment produced by impact on a planetary surface, whatever the stage of erosion of the structure. In contrast, an impact crater is the surface expression of an impact structure. In many cases, on Earth, the impact crater has been destroyed by erosion, leaving only the deformed

29.07.2016 · Impact craters and their resultant impactites are features of particular interest to many geologists, as they record the impact history of the Moon, the Earth, and the inner solar system. Without plate tectonics and heavy erosion as on Earth, impact craters on the Moon are preserved for billions of years and therefore are intriguing to many.
