- In the next few decades, the huge space rock called Apophis will pass the earth several times.
- Most people did not collide with the Earth, but a pass still gave astronomers a reason to be nervous.
- When the rock reaches the earth in 2068, it is unlikely to hit us.
There are so many space rocks surrounding our solar system that it is difficult to track them, at least for those who do not do it every day, but you may have heard of the large asteroid called Apophis before. Apophis, also known as the “God of Chaos”, is an interesting object for many reasons. One of the most important facts is that astronomers cannot rule out the possibility that rocks may actually hit the earth. Near future.
Such as Gizmodo The report points out that there is a rebound roller coaster about the possibility of Apophis hitting the earth within 48 years. At some point, the asteroid does not seem to pose a threat, but new research shows that the possibility that it may actually hit the Earth is still very small.

So, how does the forecast change? The researchers involved in this new study considered a phenomenon called the Yarkovsky effect. This is the ability of an asteroid to actually accelerate as it travels in space. This is because an asteroid like Apophis is not only a dead rock, but also contains different materials that can actually propel the rock forward. For example, radioactive material can seep out of rocks and give it a small “boost” enough to make it follow a slightly different path and pose a danger to us or other planets.
Dave Tholen, the co-author of the new study, said: “Regardless of Yarkowski’s drift, Apophis is still a threatening target, only to appear in 2068.” Gizmodo In a statement. Considering Yarkovsky, the 2068 impact scenario is still in effect. Small, but non-zero. “
Non-zero chance sounds weird, but the possibility is still very small. In terms of percentage, the probability of an asteroid hitting the Earth is about 0.00067%. However, if this rock is very lucky and humans are very unfortunate, then the collision will be devastating. This asteroid spans more than 300 meters and is full of metal. If it hits the earth, it will cause incredible damage. The asteroid will make two more distant Earth flights before 2068, and the possibility of collisions during these flights has been ruled out, but it has not been ruled out before 2068.
