Impact Event

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 event and/or impact:

    Surely one of the peculiar habits of circumstances is the way they follow, in their eternal recurrence, a single course. If an event happens once in a life, it may be depended upon to repeat later its general design.
    Ellen Glasgow (1873–1945)

    If the federal government had been around when the Creator was putting His hand to this state, Indiana wouldn’t be here. It’d still be waiting for an environmental impact statement.
    Ronald Reagan (b. 1911)
