"Skyscraper-Sized 'Potentially Hazardous' Asteroid to Buzz Past Earth Today: How to Watch Live"

An asteroid the size of the Empire State Building, designated as 2008 OS7, will pass within 1.7 million miles of Earth on Friday, with no chance of impact. Discovered in 2008, it won't return until 2032, when it will be much more distant. This harmless flyby is part of several encounters this week, including three smaller asteroids on Friday and another two on Saturday, followed by a larger asteroid on Sunday.
