Known as the Chicxulub impactor, this large object has an estimated width of 6 miles (9.6 kilometers) and produced a crater in Mexico’s Yucatan peninsula that spans 90 miles (145 kilometers).Aug 16, 2021
What Happened in Brief. According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. This impact made a huge explosion and a crater about 180 km (roughly 110 miles) across.
Originally Answered: How big was the meteor that killed all dinosaurs? About 10km in diameter and weighed roughly the same as Mount Everest, while also travelling around 6–7 times faster then a pistol bullet.
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
‘It was only around 15 million years after the non-bird dinosaurs disappear, during what’s termed the Oligocene Epoch, that we started to get really big mammals. This is when rhino-sized animals start to reappear.

The energy of the impact will vaporize the asteroid and a large amount of the Earth’s crust, creating a crater more than one hundred kilometers across, throwing all that rock into the air. Some of this debris will be going so fast that it will fly right out of the Earth’s atmosphere and go into orbit around the Earth.
On July 1 of that year, Deep Impact rendezvoused with Comet 9P/Tempel 1 (the official name is usually shortened to Comet Tempel 1). Deep Impact was about 10.8 feet (3.3 meters) long, 5.6 feet (1.7 m) wide and 7.5 feet (2.3 m) high.
An estimated 25 million meteoroids, micrometeoroids and other space debris enter Earth’s atmosphere each day, which results in an estimated 15,000 tonnes of that material entering the atmosphere each year.
From direct observation, the Chelyabinsk meteor is considered the largest meteor to have entered the Earth’s atmosphere. It appeared in 2013 and exploded with a force equivalent to 440,000 tons of TNT over Russia, impacting an area that was home to around a million people.
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
“The asteroid was about 17 meters [56 feet] in diameter and weighed approximately 10,000 metric tons [11,000 tons],” Peter Brown, a physics professor at Western University in Ontario, Canada, said in a statement.

This core, from above the crater, is what the seabed normally looks like: layers of similar looking rock laid down very slowly. These ten feet of limestone took about 10-million years to accumulate.
The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
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.
He said underground burrows and aquatic environments protected small mammals from the brief but drastic rise in temperature. … Mammals, in contrast, could eat insects and aquatic plants, which were relatively abundant after the meteor strike. As the remaining dinosaurs died off, mammals began to flourish.
A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive. Ash and gas spewing from volcanoes suffocated many of the dinosaurs. Diseases wiped out entire populations of dinosaurs.
You can visit the Museum of Science of the Chicxulub Crater in Merida, Mexico, to learn more about this crater. Scientists believe that the comet that created this crater is also responsible for creating the beautiful blue water sinkholes that dot the area around Merida.
If an asteroid the size of an apartment hits Earth, this blow could possibly destroy a small city. If an asteroid the size of a 20-storey building hits Earth, this blow can completely flatten a small country.
At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
