The passage of the asteroid Apophis by the Earth in 2029

The asteroid discovered in 2004 (considered one of the most dangerous for civilization), which scientists baptized as "Apophis," will, in principle, pass by our planet next Friday, April 13, 2029. According to the astronomers' new calculations, the space rock is three football fields wide and has a mass of more than 46 million tons, but is expected to pass at a distance of at least 35,000 kilometers from Earth, which would not pose a danger of collision.

Will the asteroid Apophis Hit Earth?

However, a new study claims that our gravity's effect would indeed cause small avalanches of rocks from the asteroid. Just as the Moon pushes and pulls on the oceans (tides), asteroids are also susceptible to this tidal force on our planet.

Current estimates suggest that the asteroid does not form a solid mass of rock but rather a large group of rocks, which would confirm this possible shower of space debris.

Here's how the theory works

To prove this hypothesis, a team of researchers from the University of Maryland (USA) has developed a computer model that has allowed them to carry out a virtual simulation taking into account both the size of the asteroid and its gravity, the force of the Earth's tides, the inertial forces, the centrifugal force caused by the asteroid's rotation as well as other similar effects.

The simulation resulted in tidal forces from the Earth that would be strong enough to cause small rock avalanches from the asteroid.

According to the calculations of the astrophysicists, this spectacle will be almost invisible as well as gradual.
"They will move very slowly because gravity is feeble on this asteroid. We'll be able to take a whole meal in peace before the avalanche ends. This is a very gentle event," explains study co-author Derek Richardson.
These disturbances on the asteroid will cause a small amount of wear on the particles on its surface.

So its passage through the Earth will be a kind of space peeling. We will be able to see in 2029, and at first, a glance will be a point of moderately bright light rushing across the sky.

2029/2036/2068 approaches

On April 13, 2029, Apophis will pass close to the Earth within geosynchronous communication satellites. Still, it will be no closer than 31 000 km above the Earth's surface.

The 2029 pass will be much closer than was predicted in 2004 when the observation arc was very short. The crossing at the end of March 2036 will be no closer than about (22×106 km), and the Earth will most likely be lost about (56×106 km).

Its effects could be 15,000 times greater than those of the Hiroshima bomb.

According to NASA, the asteroid was called "God of Chaos."

Since its discovery, experts have not stopped observing it: simulations have been reproduced on the effects of its possible collapse on Earth, which would occur at a speed of no more and no less than 19 kilometers per second. The body, classified as a Hazardous Asteroid (PAA), will cross the Indian Ocean to the United States.

Visible to the naked eye

It's rare for an asteroid that size to pass so close to the Earth. Though scientists have discovered small asteroids, ranging from 5 to 10 meters, flying at a similar distance, those about Apophis's size are much less numerous and do not pass as often.

Apophis, which looks like a point of light in the shape of a moving star, will be visible to the naked eye first in the night sky over the Southern Hemisphere, flying over the Earth from the east coast to the west coast of Australia.

Then it will cross the Indian Ocean, and already at night on the Iberian Peninsula. It will continue to move westward over Africa.

At about midnight, the object will be over the Atlantic, and it will move so fast that it will cross the ocean in one hour. By 1:00 a.m., the asteroid will have passed the United States.
