Asteroid headed toward Earth won't hit us, scientists say

Articles trending on social media are hinting at an out-of-this-world claim: that Earth is about to be decimated by an incoming asteroid.

"NASA says an asteroid bigger than a football pitch is heading towards Earth," the Wakefield Express reported.

The meaning of that sentence — aside from the term "football pitch," which is simply Britspeak for "soccer field" — seemed alarming to us.

"Dubbed ‘2016 NF23’, the gargantuan lump of space rock has been labelled ‘potentially hazardous’ by (NASA)," the article continued.  

Uh-oh. We began to wonder if Earth was on a collision course with a giant asteroid.

Turns out, the answer is no.

Close, but not that close

The Center for Near Earth Object Studies at NASA’s Jet Propulsion Laboratory keeps a database that details all instances where objects in space have had a "close approach" to the Earth. The asteroid in question, 2016 NF23, is on that list. 

According to that database, the asteroid is predicted to be closest to the Earth on Aug. 29, 2018. It will be travelling at 20,000 miles per hour, or about 5 and a half miles per second.

The database also says the asteroid is estimated to be 70 meters to 160 meters in diameter, or about 75 to 175 yards. That’s roughly the size of a soccer field.

But there’s actually no reason to worry about 2016 NF23. That’s because even at its point of closest approach to the Earth, the asteroid will be more than 3 million miles away (or, a lot of soccer fields). That’s more than 13 times the distance between the Earth and its moon.

"From an astronomical perspective, that may be close, but from a human perspective, it’s obviously not very close at all; the asteroid is certainly not ‘skimming’ past the Earth, as the story claims," said Paul Chados, the manager of the Center for Near Earth Object Studies, in an interview.  

He added, "In no way is our prediction a ‘warning,' as the story intimates."

The Wakefield Express is also incorrect in saying that 2016 NF3 "has been labelled 'potentially hazardous'" by NASA.

Alan Chamberlin, a senior engineer at the Jet Propulsion Laboratory, told PolitiFact, "The object is not classified as a PHA (Potentially Hazardous Asteroid) as defined in our CNEOS website."

That’s because the asteroid has too high of an absolute magnitude (a measurement for determining how bright asteroids appear) and is too small of an object to be considered a Potentially Hazardous Asteroid.

Both Chados and Chamberlin suggested that the article was misleading and recommended that readers who are concerned about asteroids and other objects possibly striking the Earth look at NASA’s Sentry page.

Unlike the close approach database, the Sentry page only lists asteroids "that have even the slightest chance of colliding with our planet over the next century or two," as Chados put it.

The Wakefield Express did not respond to a request for comment sent to the editorial email listed on its Contact Us page.

Our ruling

A headline on the website Wakefield Express claimed that "NASA says an asteroid bigger than a football pitch is heading towards Earth."

NASA has indeed confirmed a large asteroid is heading in the direction of Earth. But the asteroid will not actually do any damage to us. It will stay far, far, far away.

In addition, the article says that NASA has labeled the asteroid ‘potentially hazardous.’ NASA has made no such designation.

We rate this claim Mostly False.
