Scientists cannot eliminate the possibility that the asteroid Apophis will hit Earth


Several asteroids are floating around in space that NASA and other organizations are tracking. One of those asteroids is about the size of the Eiffel Tower and is called Apophis. Scientists recently said that they could not rule out that Epophys could affect the Earth in 2068.

Scientists at the University of Hawaii’s Institute of Astronomy announced that they had discovered a phenomenon called the Yarkovsky acceleration on the asteroid. This type of acceleration comes from an extremely weak force on an object due to non-uniform thermal radiation. There is an intriguing way of saying that sunlight is changing the path of the asteroid over time.

In the past, scientists have not believed that an impact scenario with Earth was likely. However, new observations indicate that the asteroid is moving away from a purely gravitational orbit at about 170 meters per year. That amount of drift is sufficient to have the potential to impact with Earth as a possibility.

Scientists have been observing the Apophis since 2004, and back in 2013, scientists announced that the asteroid would not affect the Earth in 2036. Fear had previously thought that there was a chance of influence in 2029, but this has been ruled out. Interestingly, Apophis will come closer to Earth on Friday, April 13, 2029, making it visible to the naked eye.

When this happens, astronomers will observe the trajectory of future asteroids and increase the probability of impact in 2068. Scientists have long been working on ways to deal with any potentially dangerous asteroid. The NASA DART mission would crash a spacecraft into the mood of an asteroid to see if it could be used to prevent any possible effects in the future. Researchers say there is no reason to worry about the potential impact in 2068 at this time. They say they will know well before that date what the effect will be.
