Scientists REVEAL Whether Giant Asteroid Will Collide With Earth in 2029

The Apophis asteroid was first discovered by astronomers at the Kitt Peak National Observatory in Arizona in June 2004; later that year, an Australian group of scientists managed to track the asteroid again, claiming at the time that the celestial body had a 2.7-percent chance of colliding with Earth in the future.

A 338 metre (1,110-foot )-wide asteroid known as 99942 Apophis will fly past Earth at a distance of around 19,000 miles (30,577 kilometres) on 13 April 2029, Newsweek reports.

The magazine quoted astronomers as saying that Apophis, which is named after the ancient Egyptian god of chaos, may potentially approach closer to the Earth's surface than some orbiting spacecraft. At the same time, they almost ruled out the possibility of the asteroid striking Earth.

Marina Brozovic, a radar scientist at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California described the forthcoming asteroid approach as “an incredible opportunity for science”.

“We'll observe the asteroid with both optical and radar telescopes. With radar observations, we might be able to see surface details that are only a few meters in size”, she told a session of the 2019 Planetary Defence Conference in College Park, Maryland.

Davide Farnocchia, an astronomer at the JPL's Centre for Near Earth Objects Studies (CNEOS), for his part, cited 15 years of optical and radar tracking data on Apophis, which he said helps researchers have “a very precise estimate of its orbit through the 2029 encounter with the Earth”.

“We already know that the close encounter with Earth will change Apophis' orbit, but our models also show that the close approach could change the way this asteroid spins, and it is possible that there will be some surface changes, like small avalanches”, Farnocchia said.

He underscored that although scientists cannot yet completely rule out a collision with Apophis after 2060, “those chances are extremely small, less than 1 in 100,000”.

Farnocchia added that since Apophis is bigger than an aircraft carrier, it could cause consequences on a continental level if it collided with Earth.

CNEOS director Paul Chodas, in turn, dubbed Apophis “a representative of about 2,000 currently known Potentially Hazardous Asteroids”.

“By observing Apophis during its 2029 flyby, we will gain important scientific knowledge that could one day be used for planetary defence”, Chodas noted.
