The meteorite that killed the dinosaurs was roughly 10 km (6.2 mi) in diameter.

The (suggested) size of the (possible) asteroid that killed the dinosaurs was around 10 kilometers wide. the speed and size of this object caused an explosion that was said to have been equivalent to 100 Teratons of explosives. In other words, the meteorite caused an explosion that Humanity's strongest bomb could only dream of achieving.
Let's figure it out. If the asteroid was nearly spherical and 10 km in diameter, it would have contained about 300 cubic km of rock, or about 300,000,000,000 cubic meters. One cubic meter of asteroid masses is about 3.5 tonnes, so about 1.05 trillion tonnes. Of course, it's not just the mass (weight) of an asteroid that makes the damage; it's the velocity.
The asteroid that possibly caused the extinction of all non-avian dinosaurs was thought to be a chondrite asteroid 6 miles across.
Estimates on the nature of the meteor creating the Chicxulub crater indicate that it was a stony meteorite traveling about 10 to 70 km/sec and about 10 km in diameter.
Many meteorites have hit Earth. You will need to be more specific.
it was 200000 kms
upwards of a mile wide.
The asteroid that passed nearest to the sun was the asteroid that fell to the gulf of Mexico and killed all of the dinosaurs.
An asteroid did NOT destroy the dinosaurs. A flood did. Read the Bible. :) The flood was the one who killed the dinosaurs, but Noah took small dinosaurs (e.g lizards, crocodiles).
It is not a "who" but a what that killed off the dinosaurs. It is thought that an asteroid hit the earth causing a prolonged winter which killed off all the plants so they starved to death and died.
An asteroid. This was not what killed the dinosaurs, though. The dinos were destroyed by erupting volcanoes which may or may not have been influenced by the asteroid.
700,000,000,000 Years ago, after the Dinosaurs were killed by the asteroid.
some predict the the dinosaurs died of a big asteroid.
Yucatan Peninsula
scientists don't know if an asteroid killed the dinosaurs it is just a guess the dinosaurs died 65 million years ago

No somebody had a massive dump and it killed them all

about 60 or 70% of life species plus humans will died out when if the asteroid apophis when if hit the earth that asteroid is size of manhattan same size which killed off the dinosaurs
Yes most of the people say a asteroid killed all of the dinosaurs of all time
It all depends on the size of the asteroid and the speed. When an asteroid about 6 miles in diameter slammed into the Gulf of Mexico 65 million years ago, it killed off every large lifeform on Earth, including all of the dinosaurs.

They were just fine, until a huge asteroid killed them. Thanks for asking.
The Chicxulub asteroid, which hit the Gulf of Mexico about 65 million years ago. It is said to be the asteroid that killed the dinosaurs.
