What would happen if the moon was struck by an asteroid?

Various objects hit the moon quite frequently, creating new craters on its surface. The rock that collided with the moon was only about 10 inches across. If such a rock were to head toward Earth, it would burn up in the Earth’s atmosphere and never reach the ground.

What if an asteroid the size of the moon hits the earth?

If such an object had the usual velocity, and it would have to have because no similar large objects are “synchronized” with the Earth near its orbit (which is needed for the relative speed to be much lower), the impact energy would be so high that the whole Earth would melt.

What effect did the Chicxulub impact have on Earth?

When ejected material from Chicxulub reentered the atmosphere, it carried climatically-active gases that produced sulfuric acid rain, destroyed the ozone layer, and caused greenhouse warming.

What would happen if a comet or asteroid crashed into Earth today?

“A collision between a comet and the earth would be a calamitous event. “Then dust from the impact and smoke from the fires girdles the earth, plunging our planet into a so-called impact winter.

What if the asteroid that killed the dinosaurs missed?

The event unleashed mega-tsunamis, planetwide wildfires and kicked up enough dust and debris to block the sun and cause a period of global cooling, which killed off many plants. Life would be: Still dinosauric in all likelihood, assuming no other catastrophic, extinction-level events transpired.

What would happen if the moon hit the Earth?

With the Moon coming closer, Earth’s rotation would speed up. Our days would become shorter and shorter. Global temperatures would go down, nobody would worry about climate change anymore. Unless asteroids burned the Earth to a crisp.

Did the Chicxulub asteroid cause the extinction event?

Then there’s another argument — that the Chicxulub asteroid hit the Earth too early to have caused the extinction. Researchers Gerta Keller and Markus Harting both conclude that the impact took place 300,000 years before the end of the Cretaceous period.

Why are there no impact craters on the Moon?

On Earth, impact craters are harder to recognize because of weathering and erosion of its surface. The Moon lacks water, an atmosphere, and tectonic activity, three forces that erode Earth’s surface and erase all but the most recent impacts.

Are Earth’s Chicxulub-size craters related to a primitive asteroid?

“Our hypothesis predicts that other Chicxulub-size craters on Earth are more likely to correspond to an impactor with a primitive (carbonaceous chondrite) composition than expected from the conventional main-belt asteroids,” the researchers wrote in the paper.

What would happen if the Moon was hit by a meteor?

If such a rock were to head toward Earth, it would burn up in the Earth’s atmosphere and never reach the ground. It would take another nearly moon-sized object to actually move the moon, Clark Chapman, a scientist at the Southwest Research Institute told Popsci. If that were to happen, the moon wouldn’t survive the impact.
