Definition Of ejecta

material that is forced or thrown out, especially as a result of volcanic eruption, meteoritic impact, or stellar explosion.

Melosh et al. proposed that wildfires were ignited by the thermal energy radiated by re-entering ejecta following the asteroid impact.

Example Of ejecta

  • Behind the nucleus, a broad fan of impact ejecta , backlit by the Sun, spreads out into space.

  • Fresh impact craters are surrounded by fluidized ejecta patterns, likely produced by impact into subsurface water and ice.

  • From the impact ejecta volume, he calculated a crater size of around 150 to 200 meters.

  • Impact ejecta deposits show a non-linear decrease in thickness with radial distance from the centre of the source crater.

  • Many craters are characterized by large lava-flow-like features that may represent molten ejecta flowing outward from the crater after the impact.
