How much damage did the Chelyabinsk meteor cause?
The descent of the meteor, visible as a brilliant superbolide in the morning sky, caused a series of shock waves that shattered windows, damaged approximately 7,200 buildings and left 1,500 people injured. The resulting fragments were scattered over a wide area.
What size asteroid would cause damage?
If a rocky meteoroid larger than 25 meters but smaller than one kilometer ( a little more than 1/2 mile) were to hit Earth, it would likely cause local damage to the impact area. We believe anything larger than one to two kilometers (one kilometer is a little more than one-half mile) could have worldwide effects.
How big was the biggest asteroid that hit Earth?
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 big is the Apophis asteroid?

What happened at Tunguska?
June 30, 1908 The explosion happened over the sparsely populated northern forestland above the Podkamennaya Tunguska River in what is present-day Krasnoyarsk Krai. The blast released enough energy to kill reindeer and flatten an estimated 80 million trees over an area of 830 square miles (2,150 square km).
How big was the asteroid that hit Earth in 2013?
Six years ago today, a small asteroid with an estimated size of 65 feet (20 meters) entered Earth’s atmosphere. The February 15, 2013, asteroid was moving at 12 miles per second (~19 km/sec) when it struck the protective blanket of air around our planet, which did its job and caused the asteroid to explode.
What happened to the 2013 Chelyabinsk asteroid?
Vapor cloud trail left by the Chelyabinsk, Russia, asteroid as captured by M. Ahmetvaleev on February 15, 2013. Image via ESA. After the 2013 meteor exploded, it’s said that local residents and schoolchildren found meteorite fragments left in its aftermath, many located in snowdrifts.
What was the most powerful explosion caused by an asteroid?
Still, the February 15, 2013, Russian superbolide was extremely powerful. It was later said to be the most powerful explosion caused by an asteroid since the Tunguska event, which flattened a wide area of forest and killed reindeer in Siberia in 1908. The Tunguska event happened in a sparsely populated part of Siberia.
What was the speed of the meteor that hit Earth?
Preliminary estimates released by the Russian Federal Space Agency indicated the object was an asteroid moving at about 30 km/s in a “low trajectory” when it entered Earth’s atmosphere. According to the Russian Academy of Sciences, the meteor then pushed through the atmosphere at a velocity of 15 km/s.
