How big was asteroid that hit Russia?
“The asteroid was about 17 meters [56 feet] in diameter and weighed approximately 10,000 metric tons [11,000 tons],” Peter Brown, a physics professor at Western University in Ontario, Canada, said in a statement.
How loud was the Chelyabinsk meteor?
Asteroid impacts on the Earth can be very loud when they break up in the atmosphere, like Chelyabinsk, captured in this video: The Chelyabinsk asteroid break-up was estimated to be about 180dB at 3 miles, and was detected as far as 9000 miles away.

What if the Chelyabinsk meteor hit the ground?
Chelyabinsk Meteor While the atmosphere absorbed most of the object’s energy, it resulted in major shock waves that shattered glass, damaged buildings and even caused 1,500 injuries. If the energy wasn’t absorbed, the impact could have been 26-33 times greater than the nuclear blast at Hiroshima.
How big of an asteroid would it take to destroy the Earth?
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.
What’s the biggest meteor to hit Earth?
The Chelyabinsk meteor
The Chelyabinsk meteor was estimated to have caused over $30 million in damage. It is the largest recorded object to have encountered the Earth since the 1908 Tunguska event. The meteor is estimated to have an initial diameter of 17–20 metres and a mass of roughly 10,000 tonnes.
How did alligators survive the asteroid?
These tiny creatures relied not on living green plants, but on dead leaves and bark falling from the trees, or being blown and washed in from elsewhere. So just like the crocodiles, our tiny ancestors survived the asteroid partly because they didn’t depend heavily on living plants.
Can Earth survive an asteroid?
Nuclear bombs could pulverize parts of the asteroid, forming smaller chunks that will miss Earth entirely or burn up in the terrestrial atmosphere. For asteroids about the size of one kilometer, rockets and nuclear weapons are already advanced enough to successfully intercept and destroy the celestial body completely.
