Four asteroids will zoom past Earth on Friday - including one space rock as big as a skyscraper that will pass within 1.7 million miles of our planet, scientists say.
The harmless flyby is one of several encounters this week. Three much smaller asteroids also will harmlessly buzz Earth on Friday, no more than tens of yards across, with another two on Saturday. On Sunday, an asteroid roughly half the size of 2008 0S7 will swing by, staying 4.5 million miles away.
