Asteroid in Close Approach to Earth
An asteroid that was only spotted on Sunday (Feb. 4) by the Catalina Sky Survey passed close by Earth yesterday. Early estimates of 2018 CB's size range between 50 and 130 feet (15 and 40 m) in diameter. The object flew by Earth at about 5:30 p.m. EST (2:30 p.m. PST) at less than 20 percent of the distance from the Earth to the moon. That's about 238,855 miles (384,400 km) from us. The asteroid was larger than the one that exploded over Chelyabinsk, Russia on February 15, 2013.
