An impact event is the collision of a large meteorite, asteroid, comet, or other celestial object with the Earth or another planet. Throughout recorded history, hundreds of minor impact events (and exploding bolides) have been reported, with some occurrences causing deaths, injuries, property damage or other significant localised consequences. There have also been major impact events throughout the Earth's history which severely disrupted the environment and caused mass extinctions.
Impact events have been a plot and background element in science fiction since knowledge of real impacts became established in the scientific mainstream.

Famous quotes containing the words impact and/or event:
“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
“The vanishing volatile froth of the present which any shadow will alter, any thought blow away, any event annihilate, is every moment converted into the Adamantine Record of the past.”
—Ralph Waldo Emerson (1803–1882)
