Asteroid shaves past Earth at one-fifth the distance to Moon
Asteroid 2018 CB, estimated to be around 15-40 metres in size, safely flew past Earth making a closest approach of about 64,000 kilometres, nearly one-fifth the average Earth-Moon distance, on Saturday at 4:00 am IST, NASA revealed. "Asteroids of this size do not often approach this close to our planet -- maybe only once or twice a year," said NASA.
