In planetary geology, the term "ejecta" includes debris ejected during the formation of an impact crater. When an object massive enough hits another object with enough force, it creates a shockwave that spreads out from the impact. The object breaks and excavates into the ground and rock, at the same time spraying material known as impact ejecta.
While the chains of craters observed on Earth's moon often radiate from major craters and are commonly believed to have been created by secondary impacts of the material ejected from the main collision, those present on the Jovian moons are not connected to a main crater, and it is likely they were created by the impact of a series of cometary ...
Earth is bidding farewell to a tiny asteroid that joined its orbit for nearly two months. ... He said the leading theory suggests the asteroid was ejected from the moon's surface after one of the ...
If a separate proto-planet Theia had existed, it probably would have had a different oxygen isotopic signature than Earth, as would the ejected mixed material. [51] The Moon's titanium isotope ratio (50 Ti/ 47 Ti) appears so close to Earth's (within 4 ppm), that little if any of the colliding body's mass could likely have been part of the Moon ...
A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020, 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [1]
The Moon's heavily cratered far-side. The origin of the Moon is usually explained by a Mars-sized body striking the Earth, creating a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternative explanations, and research continues into how the Moon came to be formed.
A blanket of ejecta is formed during the formation of meteor impact cratering and is composed usually of the materials of that are ejected from the cratering process. Ejecta materials are deposited on the preexisting layer of target materials and therefore it form an inverted stratigraphy than the underlying bedrock.
