The largest asteroid predicted to pass by planet Earth this year will be at its closest in March 21, according to scientists, but there's no reason to fret about it getting too close.
The asteroid, named 2001 FO32, will be about 1.25 million miles from Earth at its closest point March 21. That's more than five times the distance between Earth and the Moon.
While that grants the celestial objects the designation of a "potentially hazardous asteroid" by NASA's Planetary Defense Coordination Office, the proximity is mostly scientifically significant for astronomers. There's no predicted threat now or for several centuries, officials say.
The asteroid will hurdle past the planet at 77,000 mph, officials said. It picks up speed while traveling through the solar system during its orbit around the sun. The asteroid completes one orbit every 810 days.
The next closest encounter Earth will have with 2001 FO32 will be in 2052 when it will pass about 1.75 million miles away.
