Asteroid 'Apophis' expected to hit Earth in 2068

Astronomers have revealed that a large asteroid named 'Apophis' is expected to pass extremely close or may hit the Earth in 2068 according to foreign reports. 

The reports stated that researchers at the University of Hawaii Institute for Astronomy (IfA) in the US, have announced the detection of Yarkovsky acceleration on the near-Earth asteroid Apophis.

Prior to the detection of Yarkovsky acceleration on Apophis, astronomers had concluded that a potential impact with Earth in 2068 was impossible. The detection of this effect acting on Apophis means that the 2068 impact scenario is still a possibility.

Apophis is noteworthy because of its extremely close approach to the Earth on April 13, 2029, when the 300 metre-sized asteroid will become visible to the unaided eye as it passes within the belt of communications satellites orbiting the Earth.
