“An asteroid similar in size to one that exploded more than 100 years ago in Russia’s Tunguska region in Siberia gave Earth a close shave on Sunday (April 15), just one day after astronomers discovered the object.
The asteroid, designated 2018 GE3, made its closest approach to Earth at around 2:41 a.m. EDT (0641 GMT), whizzing by at a distance of 119,400 miles (192,000 kilometers), or about half the average distance between Earth and the moon, according to NASA’s Center for Near Earth Object Studies (CNEOS).
NASA estimated that this asteroid measures 157 to 360 feet (48 to110 meters) wide, making the space rock up to 3.6 times the size of the one that leveled 500,000 acres (2,000 square kilometers) of Siberian forest when it exploded over Tunguska in 1908.”
