∙ 13y agoThe impact of a massive asteroid has both prompt and long-term effects; depending on the mass and speed of the impactor, the immediate effect would be similar to the explosion of a massive nuclear bomb. (The small asteroid or comet which struck near Tsunguska, Siberia in 1908 was calculated to have been approximately equal to a 10 metagon nuclear explosion!) The blast energy would cause a massive fireball, consuming everything nearby, and flattening trees for miles around.
If the asteroid were to strike water - and the Earth is 3/4 covered with water - it could cause an enormous tsunami wave. There are intriguing suggestions that an asteroid impact in the Indian Ocean 5000 years ago, at a spot now called the Burckle Formation, may have generated tsunami waves that inundated everything from Madagascar to western Australia, and may have provided the background of the Great Flood legends of The Bible and the Book of Gilgamesh.
If the impactor were large enough, it could send so much dust and dirt into the atmosphere that little or no sunlight would be able to warm the planet, causing a worldwide ice age. With no sunlight, plants would be unable to grow; without plants, most large plant-eating animals would also become extinct. This is what we believe happened about 65 million years ago, when an asteroid perhaps 10 miles long struck the Earth near the tip of the Yucatan Peninsula, near the village of Chicxulub , Mexico.

∙ 13y agoAsteroid impacts have had significant impacts on Earth's history, including causing mass extinctions like the one that wiped out the dinosaurs. Some impacts have also shaped the planet's surface by creating impact craters and contributing to geological processes. Studies of asteroid impacts can provide insights into Earth's past climate, evolution, and even the potential risks of future impacts.

The scientific term for a shooting star that hits Earth's surface is a meteorite. It is a solid piece of debris from a comet, asteroid, or meteoroid that survives its passage through the Earth's atmosphere and impacts the surface.
Yes, Earth has been hit by asteroids in the past. One of the most famous examples is the Chicxulub impact that occurred around 66 million years ago, leading to the extinction of the dinosaurs. More recently, in 2013, an asteroid exploded over Chelyabinsk, Russia, causing damage and injuries.

A meteor.
When an asteroid or comet crosses Earth's orbital path but doesn't collide with it, it's often due to the object passing through a different point in space at a different time than Earth. Additionally, the vast majority of space around Earth is empty, so the chances of a direct collision are very low. Astronomers track these objects closely to assess any potential collision risk.

The scientific term for a shooting star that hits Earth's surface is a meteorite. It is a solid piece of debris from a comet, asteroid, or meteoroid that survives its passage through the Earth's atmosphere and impacts the surface.
A meteoroid is a solar system object that enters Earth's atmosphere and becomes very hot due to friction with the air. As it travels through the atmosphere, the meteoroid heats up and creates a bright streak of light called a meteor, commonly known as a shooting star.
