Why on June 30th? <\/strong><\/h3>\n\n

It was established to celebrate June 30th as the day of asteroids. It’s understandable to celebrate Mother’s Day, International Women’s Day, birthdays, Christmas, Easter… but Asteroid Day? Indeed, why do we celebrate Asteroid Day?<\/p>\n\n

The most powerful explosion that occurred on Earth happened on 30\/06\/1908. Then, an asteroid, meteoroid, or comet as it entered Earth’s atmosphere exploded and broke into pieces. The explosion occurred over Tunguska<\/a> in Siberia, and it had the energy of several megatons of TNT. For example, 1 ton of TNT (approximately equal to 4184 joules) is the energy released during an explosion. It was like having 1000 atomic bombs of Hiroshima falling together!<\/p>\n\n

A very informative video is the next one, showing another meteorite that fell in Siberia in 2013. The meteorite of 2013 was very small, as they say in the video. <\/p>\n\n
