Asteroid 2002 AJ129 – which at 0.7 miles is wider than the tallest building in the U.S. (New York's One World Trade Center) stacked on top of itself – is predicted to miss our planet, according to Metro. However, it will pass relatively close in terms of outer space.
NASA classifies any space object surpassing 459 feet wide and passing within 4,660,000 miles of Earth as "hazardous," according to a 2013 report on the space agency's website. There are about 1,000 such known space objects monitored by NASA.
This asteroid is more than eight times wider than the minimum (3,696 feet) and will pass within just over half the minimum distance (2,615,128 miles) to our planet.
For a reference point, the moon orbits Earth at a distance of about 238,855 miles.
