Asteroid larger than New York's Empire State Building to buzz Earth on Friday

 An asteroid the size of a skyscraper will pass within 1.7 million miles of Earth on Friday.

Don't worry: there is no chance of it hitting us as it will travel seven times the distance from Earth to the Moon.

NASA's Center for Near Earth Object Studies estimates the space rock to be between 690 feet and 1,575 feet across.

NASA says lost asteroid 2007 FT3 is unlikely to hit Earth in 2024.

This means the asteroid could be similar in size to New York City's Empire State Building or Chicago's Willis Tower.

This asteroid, discovered in 2008, has been designated as 2008 OS7. It won't cross our path again until 2032, but it will be a much more distant encounter, staying 45 million miles away.

NASA says it's tracking newly discovered 161-foot asteroid that has a 'very slim chance' of hitting Earth

The harmless flyby is one of several encounters that have occurred this week. Three very small asteroids will also harmlessly circle Earth on Friday, no closer than tens of yards, and two more on Saturday. On Sunday, an asteroid about half the size of 2008 0S7 will fly past 4.5 million miles away.
