by Two small asteroids recently discovered by astronomers at the NASA-funded Catalina Sky Survey (CSS) near Tucson, Arizona, are safely passing by Earth within one lunar distance this week.
The first of this week’s close-approaching asteroids -- discovered by CSS on Feb. 4 -- is designated asteroid 2018 CC. Its close approach to Earth came Tuesday (Feb. 6) at 12:10 p.m. PST (3:10 p.m. EST) at a distance of about 114,000 miles (184,000 kilometers). The asteroid is estimated to be between 50 and 100 feet (15 and 30 meters) in size.
Of potentially greater interest is asteroid 2018 CB, which will also pass closely by Earth on Friday, Feb. 9, at around 2:30 p.m. PST (5:30 p.m. EST), at a distance of about 39,000 miles (64,000 kilometers), which is less than one-fifth the distance of Earth to the Moon). The asteroid, which is estimated to be between 50 and 130 feet (15 and 40 meters) in size, was also discovered by CSS on Feb. 4.
