Tag: impact event

An impact event is a collision between celestial objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal impact. When large objects impact terrestrial planets like the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact structures are dominant landforms on many celestial solid objects and present the strongest empirical evidence for their frequency and scale. In fiction, an impact event is a common way to end the world as we know it, either through the impact itself or through its aftermath, and it may happen either naturally or through human hands; this may include man-made objects, such as space debris and fictional space colonies.
