The 110-metre long asteroid, which has been dubbed 2018 GE3 by NASA, shot by just 192,500km away – half the distance between the Earth and the Moon. Technically, the term NEO means a space object that comes within 30 million miles of our planet. As, Live Science reported, the chemical composition of some asteroids makes them less reflective to be observed from ground based optical telescopes.
Eddie Irizarry of the Sociedad de Astronomía del Caribe (Astronomical Society of the Caribbean) has been a NASA Solar System Ambassador since 2004. Asteroid 2018 GE3 is measured between 155 and 330 feet (48 to 100 meters) across. They were also said to have felt the heat that was radiating from the area when the explosion occurred.
