How strong is the meteor that killed the dinosaurs?

The Chicxulub impactor had an estimated diameter of 11–81 kilometers (6.8–50.3 mi), and delivered an estimated energy of 21–921 billion Hiroshima A-bombs (between 1.3×1024 and 5.8×1025 joules, or 1.3–58 yottajoules).

Is there anything stronger than a hydrogen bomb?

Two teeny tiny particles can theoretically collide to create a “quarksplosion” with eight times more energy than the reaction that powers hydrogen bombs, according to a new paper published in the journal Nature.

Whats stronger than a nuclear bomb?

But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. The U.S. witnessed the magnitude of a hydrogen bomb when it tested one within the country in 1954, the New York ​Times​ reported.

How big was the asteroid that hit the earth 66 million years ago?

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.

What killed the dinosaurs?

New theory behind Chicxulub impactor that killed the dinosaurs – Harvard Gazette.

Was Tyrannosaurus Rex alive when an asteroid hit?

Tyrannosaurus Rex was alive at the time of the asteroid strike. Ever since the realisation that many years ago, huge, reptilian animals walked the Earth, scientists have been trying to find out what caused them to become extinct. Palaeontologists discovered that after a point around 66 to 65 million years ago there were no more dinosaur fossils.

How big was the asteroid that caused the Cretaceous–Paleogene extinction event?

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. A common comparison is that the asteroid would have been ‘ the size of Manhattan ’.

How much would an asteroid explode if it hit Earth?

The asteroid would have been travelling at around 20 kilometres (12.5 miles) per second, or 72,000 kilometres / 44,712 miles per hour. The impact would have caused an explosion equivalent to 100 million megatons of TNT (4.2×10 23 Joules)
