‘Potentially hazardous asteroid’ bigger than Earth’s tallest building will zoom past us next month

2002 AJ129 is expected to be the largest and speediest space object to whiz past the Earth in 2018.

A “potentially hazardous asteroid” known as 2002 AJ129 is set to fly by Earth at a whopping 67,000 miles per hour next month — but there is no need to worry, scientists say.

The 0.7-mile long body ─ larger than the tallest building on Earth, Dubai’s half-mile high Burj Khalifa skyscraper ─ will rocket past our planet on Feb. 4 by 2.6 million miles, giving it no chance of hitting us.

Potentially hazardous asteroids, or PHAs, are not uncommon. According to a 2013 report on NASA’s website, there are over 1,000 PHAs out there and possibly more yet to be discovered.

PHAs are defined by NASA as Near-Earth Asteroids “whose Minimum Orbit Intersection Distance (MOID) with the Earth is 0.05 [in astronomical units] or less and whose absolute magnitude is 22.0 or brighter.”

One astronomical unit is 149,597,870,700 miles, or approximately the average distance between the Earth and the Sun.

2002 AJ129 is expected to be the largest and speediest space object to whiz past the Earth in 2018, according to the Atlanta Journal Constitution.

NASA has not yet responded to a request for comment from Fox News.

Astronomers almost unanimously agree that no asteroid, particularly those of the near-Earth variety, will hit our planet in our lifetime. However, if one of this size were to hit us, it could cause some serious damage.

When discussing the 3-mile wide 3200 Phaethon, which flew past Earth in mid-December, Boston University astronomy professor Michael Mendillo told Time that an asteroid of this size “would be this kind of object that would cause a catastrophic collision, should there be one,” before adding that it is highly unlikely.

In addition to the aforementioned 3200 Phaethon and 2002 AJ129, Earth has had some close-calls with giant space rocks in recent months.

In August 2017, a 2.7-mile wide asteroid dubbed Florence passed by Earth at a safe distance of 4.4 million miles, roughly 18 times the distance between Earth and the moon. And in October, 2012 TC4, a space rock estimated to measure between 50 and 100 feet, passed safely past Earth by 26,000 miles and was used to test Earth’s international warning network.

Saving humanity 

If an asteroid were to ever threaten the Earth, NASA has a plan to fight it off.

In June, the agency unveiled a video using 3-D modeling techniques and one of its supercomputers in an effort to produce simulations on a variety of asteroid impact scenarios.

The work is being done by experts on the Asteroid Threat Assessment Project at the NASA Advanced Supercomputing facility at Ames Research Center in California’s Silicon Valley. The efforts are in conjunction with NASA’s Planetary Defense Coordination Office.

The research has been shared with a number of different parties, including university scientists, national research labs and different government agencies.

The work follows an asteroid collision in 2013 in the Russian city of Chelyabinsk. The blast from the asteroid injured more than 1,200 people and damaged buildings 58 miles away.

Separately, in 2016, NASA opened a new office to track asteroids and comets that come too close to Earth, known as the Planetary Defense Coordination Office (PDCO).

NASA has been studying Near-Earth Objects (NEOs) since the 1970s. According to the PDCO, NASA-funded survey projects have found more than 95 percent of the known catalog of over 15,000 NEOs.
