    Ejecta features are classified based on their distance from the impact crater, the appearance of the ejected material, and the geomorphological characteristics of the terrain. Some common ejecta features include ejecta blankets, radial and concentric ejecta patterns, and secondary craters.

  2. Mar 1, 2023 · Examples of ejecta in a Sentence. Recent Examples on the Web Figuring out exactly what went on regarding this ejecta is complicated, though. John Timmer, Ars Technica, 1 Mar. 2023 So, the equal and opposite reaction to the ejecta would be a slowing down of the asteroid's orbit, which would be added to the effect of DART's impact.

  3. Jan 1, 2014 · Radial ejecta has two facies: (1.1) continuous (proximal) ejecta and (1.2) discontinuous (distal) ejecta. The continuous ejecta deposits form primarily from larger and slower materials, while distal ejecta deposits comprise smaller and faster ejected materials (Oberbeck 1975).

    Nov 16, 2021 · In astrophysics, ejecta is the gaseous material expelled from a star, either quiescently (e.g., in coronal mass ejection or through the wind of an evolved star, like a red giant or an AGB star) or in a stellar explosion like in a supernova or nova.

  5. Ejected matter, especially from an erupting volcano. Volcanic ejecta usually includes volcanic glass, ash, and rock fragments.

  6. Meteorite crater - Impact Process, Ejecta, Shockwaves: When an asteroidal or cometary object strikes a planetary surface, it is traveling typically at several tens of kilometres per second—many times the speed of sound. A collision at such extreme speeds is called a hypervelocity impact.

  7. Mar 1, 2023 · Distal ejecta with non-radial distributions are an inherent product of planetary impacts, and their unobvious provenances could mislead stratigraphic interpretations and hamper age estimations ...
