## How many megatons is Chicxulub?

100 million megaton
The Chicxulub impact event was an ~100 million megaton blast that devastated the Gulf of Mexico region. The blast generated a core of superheated plasma in excess of 10,000 degrees. Although that thermal pulse would have been relatively short-lived, a handful of minutes, it would have been lethal for nearby life.

## How much energy did the Chicxulub asteroid release?

The kinetic energy of the impact was estimated at 100 teratons of TNT, more than 4.5 billion times the energy of the atomic bomb dropped on Hiroshima, Japan.

How much did the Chicxulub asteroid weight?

The mass is in the range of 1.0e15 kg to 4.6e17 kg. Finally, the diameter of the object is in the range of 10.6 km to 80.9 km….Assessments of the energy, mass and size of the Chicxulub Impactor.

### How many megatons was the meteor that killed the dinosaurs?

100 million megatons
The energy released by the impact that blew out the Chicxulub crater was equivalent to about 100 million megatons, many orders of magnitude greater than the nuclear explosion at Hiroshima, a 15-kiloton blast.

### How many megatons was Tzar Bomba?

50 megatons
Yielding an explosion of 50 megatons the “Tsar Bomba,” as it is sometimes called, was about 3,300 times more powerful than the 15 kilotons nuclear weapon dropped on Hiroshima.

How many tons of TNT was the asteroid that killed the dinosaurs?

An instant later, the asteroid slams into Earth with an explosive yield estimated at over 100 trillion tons of TNT. The impact penetrates Earth’s crust to a depth of several miles, gouging a crater more than 115 miles (185 kilometers) across and vaporizing thousands of cubic miles of rock.

## How much energy would an asteroid affect to Earth’s surface?

The airburst of the 17-meter Russia asteroid released as much energy as nearly 500 kilotons of TNT 20-30 kilometers above the surface, knocking out windows for many kilometers around. If DA14 had hit, it would have released the energy equivalent to 2.4 megatons of TNT.

## How big was the asteroid that killed the dinosaurs TNT?

10 km
65 million years ago, an asteroid 10 km in diameter struck Mexico’s Yucatan Peninsula. The asteroid and its 100 km diameter crater have the Mayan name Chicxulub…but you might know it as “The Asteroid that Killed the Dinosaurs”.

How powerful was the asteroid 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.

### How much did the Tsar Bomba weight?

27 tons
The resulting weapon weighed 27 tons, with a length of some 26 feet (8 metres) and a diameter of about 7 feet (2 metres). Although officially known as RDS-220, it acquired numerous nicknames, most notably Tsar Bomba in the West.

### How many kilotons was Tsar?

Yielding an explosion of 50 megatons the “Tsar Bomba,” as it is sometimes called, was about 3,300 times more powerful than the 15 kilotons nuclear weapon dropped on Hiroshima.
