How much did the meteor that killed the dinosaurs weigh?

They worked out that such an asteroid would have weighed at least 34 billion tonnes and measured around 7km in diameter, producing a crater around 100–200km across.

What was the density of the asteroid that killed the dinosaurs?

2,630 kilograms per cubic meter
In the researchers’ simulations, they modeled an asteroid measuring about 11 miles (17 km) in diameter, traveling at approximately 27,000 mph (43,000 km/h) and with a density of 164 lbs. per cubic foot (2,630 kilograms per cubic meter).

How big was the rock that killed the dinosaurs?

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.

Did any dinosaur survive the meteor?

The results of this study, which were based on estimated real global biodiversity, showed that between 628 and 1,078 non-avian dinosaur species were alive at the end of the Cretaceous and underwent sudden extinction after the Cretaceous–Paleogene extinction event.

What if asteroid hit sun?

The crash would unleash as much energy as a magnetic flare or coronal mass ejection, but over a much smaller area. “It’s like a bomb being released in the sun’s atmosphere,” Brown says.

How big was the asteroid that wiped out the dinosaurs?

The Chicxulub crater, formed by an asteroid impact that would ultimately wipe out the dinosaurs, is about 150 kilometers (93 miles) wide.

Could dinosaurs have survived the giant asteroid?

Dinosaurs would have survived the asteroid if it struck seconds earlier or later – rather than hitting shallow coastal waters. An impact in the nearby Atlantic or Pacific Oceans would have meant much less vaporised rock. Cloud would have been less dense and sunlight could still have reached the planet’s surface.

What was the largest asteroid ever found?

The largest asteroid ever recorded has passed Earth at a distance of 145 million miles, giving scientists the opportunity to learn more about its physical characteristics. The 2.7-mile wide astral body, called Florence, will not approach the planet this close again until 2500.

What is the size of the meteor that killed the dinosaurs?

If you’ve found this page simply wanting to know how big the asteroid that killed the dinosaurs was, here are the basics: The asteroid believed responsible for the Cretaceous-Paleogene Extinction Event is estimated to have been between 10 and 15 kilometres (6 and 9 miles) across.
