Cratering on WitrynaImpact craters are a ubiquitous feature of asteroid surfaces. On a local scale, small craters puncture the surface in a way similar to that observed on terrestrial planets and the Moon. At the opposite extreme, larger craters often approach the physical size of asteroids, thus globally affecting their shapes and surface properties. Crater …
Witryna5 paź 2016 · Introduction. One of the most elementary processes in the solar system is the collision of solid bodies, which is documented by numerous observations of impact craters on nearly all planets, moons, and asteroids analyzed so far, as well as by 188 confirmed craters on Earth (Earth Impact Database 2016).Most planetary surfaces … Witryna18 maj 2024 · Impact heating on asteroid parent bodies may be sufficient to facilitate aqueous alteration and the generation of solid organic material in the region below the …
WitrynaParticles emanating from comet 81P/Wild 2 collided with the Stardust spacecraft at 6.1 kilometers per second, producing hypervelocity impact features on the collector surfaces that were returned to Earth. The morphologies of these surprisingly WitrynaThe manner in which an impact crater and its ejecta blanket are created involves an interplay between gravity and the strength properties of the target material. Gravity is important because the overburden stress at depth in an asteroid determines the material shear strength, which affects the mechanics of crater and ejecta formation. This has …
