Earth dodged another close one Saturday.

A giant asteroid whizzed by our planet at a speed of 40,000 mph, The Telegraph reported.

The asteroid passed us by 15 million miles — about half the distance to Mars.

A strike by the 1.5-mile-wide heavenly body — with the ungainly name 86666 (2000 FL 10) — would have been catastrophic, according to NASA scientists.
