Apofis, the “God of chaos”, who is in orbit near the Earth, has a small chance of hitting Earth in the next 50 years. Astronomers observing the giant asteroid closely said that the speed of Apofis has recently increased and the close pass calculated for the year 2068 could turn into an impact. But the odds still seem very low for now.
The increasing speed of the apophid is attributed to the force we call the “Yarkovsky effect”, which is widely observed in space. In Apophis, the yarkovsky effect was created due to the warming of the Sun of some parts of the asteroid compared to other parts. The orbit of the asteroid is said to have changed slightly and its speed has increased due to the asymmetric heat dissipation resulting from this situation.

In previous calculations, scientists had estimated the likelihood of Apophis hitting Earth in 2068. 150,000 ‘of 1 as explained. Now this chance a little more That said. However, the probability is still very low. It is stated that there is no situation to worry about.

University of Hawaii astronomer David Tholen, who made some statements on the subject,“When we first discovered Apophis, our calculations showed that the probability of a collision was almost zero in 2068. However, these calculations did not take into account the Sun’s energy. The impact scenario for 2068 is still valid. . our very careful and careful examination needs. “ he used expressions.
The asteroid Apophis is expected to pass very close to Earth in 2029. In a statement released last year, it was claimed that Apofis will approach Earth by 30,000 kilometers in 2029. 30,000 kilometers, an unusually close distance, especially for a giant asteroid like Apofis. Asteroids that pass through locations up to 30,000 kilometers from Earth are generally very small in size, 5-10 meters wide. Therefore, the transition of Apofis in 2029 will be very important for the world of astronomy.
David Tholen said that with the information obtained after the close transition in 2029, it is possible to make better predictions for 2068. The calculations made now will likely continue to change in the coming period.
Asteroid Apophis discovered in 2004 340 meters have a width. According to the statement made by the scientists, Apophis hit the Earth, 880 million tons of TNTIt will release an energy equivalent to the explosion of at the same time. We are talking about 65,000 times the explosion power of the Hiroshima nuclear disaster.
