Remember that meteor that exploded over Russia just 4 days ago? It caused havoc in Chelyabinsk, Russia when 1,200 people and 3,724 buildings were damaged.
Videos flooded the internet on the day of the impact that gave the rest of the world an idea of what the meteor looked like. After watching one of the videos, it is hard to imagine the size of the meteor. Take a look:
After a careful investigation by NASA thanks to a worldwide network of sensors, we can get a better estimate on how big this meteor was. Before the meteor entered the Earth’s atmosphere, NASA believes that it was 55 feet (17 meters) in size.
Previously, the object was only believed to have released 30 kilotons of energy. Now, with the help of 5 infrasound stations located around the world, the estimate has been raised to nearly 500 kilotons of energy released. This number of over 30 times greater than the amount of energy that the “Little Boy” released in Hiroshima.
With the new data, NASA has concluded that the Russia meteor is “the largest reported since 1908, when a meteor hit Tunguska, Siberia”. But before you start to worry and build an underground shelter, NASA believes that an event such as this is only to occur once every 100 years.
How do you feel about meteors and asteroids playing in our atmosphere? Do you think that NASA and all governments should expand their programs to better protect against these objects? Let us know in the comments below. [ Source ]
