After its discovery in 2004, the asteroid 99942 Apophis or the Apophis asteroid. It was identify as the most dangerous asteroid that could threaten the Earth. But the new appraisal has change. When astronomers from NASA . Who track the Apophis’ journey and orbit Reveal there was no risk that apophis would affect our planet for at least a century or 100 years.
Astronomers have previously estimated that the asteroid apophis It may be a serious threat to the world. It is predict to approach on April 13, 2029, it will be less than 32,000 kilometers from the Earth’s surface, but from observations of objects near the Earth NEO. (NEO-Near-Earth Object) on March 5, it was found that the risk expect in the year 2029 has been eliminate. And the calculations do not show that there will be any risk from it for at least the next 100 years.
The apophis is a two-wavy, peanut-shaped asteroid. This is a shape that is most common in asteroids near the Earth. It is more than 200 meters in diameter. However, astronomers continue to study the spin rate of asteroids. This allows to direct the asteroid when it meets the Earth’s gravitational field in 2029 that can change its rotational state and cause so-called asteroid quakes.
