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:
“Television does not dominate or insist, as movies do. It is not sensational, but taken for granted. Insistence would destroy it, for its message is so dire that it relies on being the background drone that counters silence. For most of us, it is something turned on and off as we would the light. It is a service, not a luxury or a thing of choice.”
—David Thomson, U.S. film historian. America in the Dark: The Impact of Hollywood Films on American Culture, ch. 8, William Morrow (1977)
“The event combined with
Beams leading up to it for the look of force adapted to the wiser
Usages of age, but it’s both there
And not there, like washing or sawdust in the sunlight,
At the back of the mind, where we live now.”
—John Ashbery (b. 1927)
