Dino-killing asteroid: How big was it? The dimensions of Chicxulub Crater — about 90 miles wide by 12 miles (20 km) deep — give us a rough idea of the impactor's size. For example, Siraj and Loeb calculated that the incoming object was likely about 4.3 miles (7 km) wide.Aug 16, 2021

How big is the crater from the asteroid that killed the dinosaurs?
The asteroid is thought to have been between 10 and 15 kilometres wide, but the velocity of its collision caused the creation of a much larger crater, 150 kilometres in diameter — the second-largest crater on the planet.
How big was the rock that killed the dinosaurs?
The asteroid was about 7.5 miles (12 kilometers) in diameter and was traveling about 27,000 mph (43,000 km/h) when it created a 124-mile-wide (200 km) scar on the planet's surface, said Sean Gulick, a research professor at the University of Texas Institute for Geophysics, who led the study.
Can you see the Chicxulub crater?
The Chicxulub crater is not visible at the Earth's surface like the famous Meteor Crater of Arizona. There are, however, two surface expressions of the crater. Radar measurements captured from one of NASA's space shuttles detected a subtle depression in the sediments that bury the crater.
How big is the dinosaur crater?
It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it's known, was a plummeting asteroid or comet that left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep.
How big of an asteroid would it take to destroy the earth?
about 96 km Ultimately, scientists estimate that an asteroid would have to be about 96 km (60 miles) wide to completely and utterly wipe out life on our planet.
What survived the dinosaur extinction?
Birds Birds: Birds are the only dinosaurs to survive the mass extinction event 65 million years ago. Frogs & Salamanders: These seemingly delicate amphibians survived the extinction that wiped out larger animals. Lizards: These reptiles, distant relatives of dinosaurs, survived the extinction.
How big of an asteroid would it take to destroy the Earth?
about 96 km Ultimately, scientists estimate that an asteroid would have to be about 96 km (60 miles) wide to completely and utterly wipe out life on our planet.
How big is the Yucatan crater?
The crater is estimated to be 180 kilometers (110 miles) in diameter and 20 kilometers (12 miles) in depth….Chicxulub crater.

Did Chicxulub create the Gulf of Mexico?
The Chicxulub impact into the Gulf of Mexico, over the partially submerged Yucatán Peninsula, created a radiating series of waves, including tsunamis that ramped up and towered over coastlines.
