Skull-shaped asteroid to fly past Earth again in 2018
Spain-based astronomers estimate that the skull-shaped "Halloween" asteroid which flew harmlessly by Earth on October 31, 2015, will return in November 2018. The roughly 640-metre-wide asteroid came within 4.8 lakh km, while the Earth-Moon average distance is about 3.84 lakh km. It could be an extinct comet that has lost its water after many laps around the Sun, researchers said.
