Asteroid Apophis: will it hit the Earth? 😱⁠
⁠
Out of all asteroids that can be found in the Sky Tonight app, Apophis is one of the most frequently searched for. No wonder: it was predicted to hit the Earth in 2029, so people have been keeping an eye on it ever since it was discovered.⁠
⁠
☄️ 99942 Apophis is a near-Earth asteroid that orbits the Sun about every 324 days. It was discovered in 2004. Initially, Apophis was given a 2.7% of colliding with the Earth in 2029. This prediction led to speculation linking Apophis with the biblical Wormwood, mentioned in the Book of Revelation as a star that falls from the sky, making the waters bitter and causing suffering for many. ⁠
⁠
☠️ Although further observations ruled out the possibility of impact in the near future, a doomsday atmosphere still lingers around the asteroid.⁠
⁠
🌎 On April 13, 2029 (by the way, that will be a Friday the 13th), Apophis will pass at about 31,600 kilometers of the Earth. That’s 10 times closer to us than the Moon! However, the asteroid will not hit our planet: any chance of impact is ruled out for at least the next 100 years (and even further) thanks to the observation campaign conducted in March 2021.⁠
⁠
🤩 And one more reason to be happy: on April 13, 2029, Apophis will be visible to the naked-eyed observers from Europe, Africa, and western Asia. It will look like a rather bright (mag 3) star-like object located in the constellation Cancer. If you watch it for some time, you’ll see it moving slowly (roughly the Moon's diameter per minute).⁠
