An impact event is a collision between celestial objectscausing 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 planetslike 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 of the System's solid objects and present the strongest empirical evidence for their frequency and scale.
Impact events appear to have played a significant role in the evolution of the Solar System since its formation. Major impact events have significantly shaped Earth's history, have been implicated in the formation of the Earth-Moon system, the evolutionary history of life, the origin of water on Earthand several mass extinctions. Notable impact events include the Late Heavy Bombardment, which occurred early in history of the Earth-Moon system and the Chicxulub impact, 66 million years ago, believed to be the cause of the Cretaceous-Paleogene extinction event.
Throughout recorded history, hundreds of Earth impacts (and exploding bolides) have been reported, with some occurrences causing deaths, injuries, property damage or other significant localised consequences.[1]One of the best-known recorded impacts in modern times was the Tunguska event, which occurred in Siberia,Russia, in 1908. The 2013 Chelyabinsk meteor event is the only known such event to result in a large number of injuries, and the Chelyabinsk meteor is the largest recorded object to have encountered the Earth since the Tunguska event.
The most notable non-terrestrial event is the Comet Shoemaker-Levy 9impact, which provided the first direct observation of an extraterrestrial collision of Solar System objects, when the comet broke apart and collided with Jupiter in July 1994. Most of the observed extrasolar impacts are the slow collision of galaxies; however, in 2014, one of the first massive terrestrial impacts observed was detected around the star NGC 2547 ID8 by NASA's Spitzer space telescope and confirmed by ground observations.[2]Impact events have been a plot and background element in science fiction.

The foucault pendulum provides evidence of earth?
It provides evidence of the Earth's rotation on its axis.
How did the three sources of heat prevent life from existing when the earth was formed?
the first sources of heat was asteroids and meteorites. another sources of heat for the early earth was the contraction of gravity. the third sources of energy for the early earth was radioactivity. hope this helped :)
Which layer of the earth do think shows the most evidence of an earthquake?
The lithosphere.
How are seismic waves used to provide evidence about earth's sructure?
vibrations
What part of speech is the word asteroid?
Some people think the dinosaurs died when an asteroid hit the earth.
What two objects produce meteorites?
comets and asteroids
Where do meteriods come from?
Meteoroids are rocky or metallic fragments from space that come from comets or asteroids. They can be leftovers from the formation of the solar system and are usually small in size, ranging from dust particles to boulder-sized objects. Many meteoroids enter Earth's atmosphere as meteors and may land on the surface as meteorites.
What space objects are made of chunks of rock?
Asteroids, meteoroids, and comets are space objects that are made of chunks of rock. Asteroids are rocky bodies that orbit the Sun within the asteroid belt, meteoroids are smaller rocky fragments that travel through space, and comets are a mixture of rock, dust, ice, and frozen gases.
Which is longer a meteoriod or an asteroid?
Asteroids are generally larger than meteoroids. Asteroids are rocky objects that are larger than 33 feet (10 meters) in size, whereas meteoroids are smaller rocky or metallic objects that are less than 33 feet (10 meters) in size.
A rocky space object of vairying size?
The object is likely an asteroid, meteoroid, or meteorite. Asteroids are rocky objects that orbit the Sun, meteoroids are smaller rocky objects that travel through space, and meteorites are meteoroids that survive the journey through Earth's atmosphere and reach the ground.
What objects can be seen in space from earth because the objects reflect light from another object?
Planets, moons, asteroids, artificial satellites.
Can a asteroid be the size of a pebble?
Asteroids can vary widely in size, from just a few meters to hundreds of kilometers in diameter. A pebble-sized asteroid is certainly possible, and such small objects are known as meteoroids. These small asteroids or meteoroids often burn up in Earth's atmosphere, creating shooting stars.
What are the interplanetary material that collides with the surface of the Earth?
Interplanetary material that collides with the Earth's surface includes meteoroids, asteroids, and comets. When these objects enter Earth's atmosphere and survive the journey to impact the surface, they are referred to as meteorites.
What is difference between asteroids and meteoroids?
Asteroids are rocky objects that orbit around the Sun, mostly found in the asteroid belt between Mars and Jupiter. Meteoroids are smaller rocky or metallic objects that also orbit around the Sun but are much smaller than asteroids. When a meteoroid enters Earth's atmosphere, it burns up and creates a streak of light known as a meteor.
Do asteroids comets and meteoroids pose danger to earth?
Meteoroids generally do not pose much of a risk as they are generally small enough to burn up in the atmosphere, and do not reach the surface. Asteroids and comets are larger and can cause potentially catastrophic damage if they strike Earth.
The craters on the surface of earths moon were produced by what?
The craters on the surface of the Earth's moon were produced by impacts from meteoroids and asteroids. These impact events occurred over billions of years as the moon lacks an atmosphere to protect it from incoming objects.
Does meteor and asteroids look alike?
Meteors are meteoroids that enter Earth's atmosphere and burn up, creating a bright streak of light. Asteroids are rocky objects in space that orbit the Sun, ranging in size from a few meters to hundreds of kilometers. While both meteors and asteroids are celestial objects, they have different appearances and behaviors.
