Witryna1 dzień temu · This similarity in the colors of the smallest craters on Bennu and Ryugu could mean that fresh materials on the two asteroids have the same starting point in visible wavelength colors before the effects of space weathering begin; however, the subsequent maturation trends move the colors of surface materials in opposite … Witryna1 maj 2003 · Furthermore, large craters in porous materials can apparently form without the ejecta blankets that are a familiar signature of terrestrial and lunar impact craters. The ejection of material during impact events is an important mechanism in the collisional …

Disruption of kilometre-sized asteroids by energetic collisions
WitrynaPOROSITY OF ASTEROIDS Data from a number of sources indicate that many aster-oids have significant porosity. In some cases, porosities are large enough to affect … Witrynaasteroids in order to study the effects of impact heating on the cratering processes. So, we tried to measure the temperature around the impact crater directly and … 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 … incident in horley today
