Abramov was at school in his hometown of Chelyabinsk, Russia on Feb. 15, 2013 when a meteor exploded over the city. The meteor was between 49 and 55 feet in size, with an estimated mass of 7,000 to 10,000 tons, according to CNN. The estimated energy released by the meteor's explosion was 300-500 kilotons, or about 20 times the estimated amount released by the nuclear bomb dropped on Hiroshima, Japan in 1945.
"I was in school and all the windows in my class crashed," Abramov said. "All windows in the city was gone. … It was like big panic because it was something none of us had ever seen.
