The impact triggered a seismic event with an estimated magnitude of 9–11 Mw at the impact site. A cloud of hot dust, ash and steam would have spread from the crater, with as much as 25 trillion metric tons of excavated material being ejected into the atmosphere by the blast.

How big was the asteroid that hit the dinosaurs?
roughly 10 km 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.
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.

What was the density of the asteroid that killed dinosaurs?
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.
How big was the comet that destroyed Earth?
The Chicxulub crater was formed when a large asteroid hit earth. The asteroid is believed to have been around 15 kilometers across in diameter and left a crater the size of 25,450 square kilometers that's now buried under the Yucatan Peninsula in Mexico.
How long did dinosaurs live after asteroid?
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
How big is the Apophis asteroid?
185 m99942 Apophis / Radius On Friday, April 13, 2029, Earth will experience a dramatic close encounter with the asteroid 99942 Apophis. The 1,120 feet (340-meter) wide object will pass within just 19,000 miles (31,000 km) of our home planet — a distance that brings it closer than most geostationary satellites.
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 was the tsunami that killed the dinosaurs?
The impact did generate a massive tsunami and it was one of the largest waves Earth ever experienced. The asteroid that hit the Earth 66 million years ago was 8-10 km across and traveled from the northeast at a velocity of 20 kilometers per second which is 45,000 miles per hour (!)
How long did dinosaurs survive after asteroid?
'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.
