Health is wealthEarth’s close shave with asteroid
An asteroid of the similar size of the rock exploded over Siberia in 1908 with a force of thousand atomic bombs whizzed close to earth recently. The space rock, the size of a 10-storey building, was about 115 feet wide created a colossal explosion in air above Siberia in 1908 that flattened 2000 square kilometers of forest. DD45 estimated to be between 68 and 152 feet across, raced by earth recently. The gap was just 72,000 kilometers or a fifth of the distance between earth and moon and only twice the height of satellites in geosynchronous orbit. Astronomers now know that the asteroid is moving within the inner solar system and that the space rock completes an orbit around sun every 1.56 years. This means the asteroid could swing close to Earth again someday.
