Asteroid skimming past Earth may loom larger than exploding Russian meteor

A newly discovered asteroid that will fly safely past Earth today (Feb. 9) may be larger than a celestial object that exploded over Chelyabinsk, Russia, five years ago. The newly found interloper, called 2018 CB, is estimated to be from 50 to 130 feet in diameter, and will fly by Earth at about 2:30 p.m. PST (5:30 p.m. EST).
