The LINEAR (Lincoln Near-Earth Asteroid Research) project identified the 30-meter asteroid before it passed us by 42,600 km-nearly one-tenth the distance from the Earth to the Moon. While miniature in size, the asteroid would have caused an explosion equal to hundreds of kilotons of TNT had it hit the Earth's surface. Experts would later confirm the blast would not have caused any serious ground level impact.
