Nature. 99942 Apophis asteroid
99942 Apophis is a near-Earth asteroid. It was initially observed in December 2004. It will come scarily close to Earth on Friday, April 13, 2029.
Initial observations indicated a small probability (up to 2.7%) that Apophis would strike the Earth in 2029. Later the cumulative impact probability (for the 2029 Earth encounter) was reduced to be around 0.004%.
NASA initially estimated the energy that Apophis would have released if it struck Earth as the equivalent of 1480 megatons of TNT. Later it was revised down to 880 megatons, then revised to 510 megatons. For comparison, the Tunguska event is estimated to be in the 3–10 megaton range.
April 13, 2029 and beyond
On April 13, 2029, asteroid 99942 Apophis will pass Earth 23,000 miles (37,000 km) above the ground. For comparison, geosynchronous satellites orbit is at 22,300 miles (36,000 km).
Apophis is probably going to return back to Earth in 2036. Its likely collision with Earth may occur on April 13, 2036. At this time the ability to calculate the Apophis's orbit is blurred out by the 2029 Earth encounter.
Our ability to 'see' where 2004 MN4 will go (by extrapolating its orbit) is so blurred out by the 2029 Earth encounter, it can't even be said for certain what side of the sun 2004 MN4 will be on in 2035. Talk of Earth encounters in 2035 is premature.

This should be scary enough
“The world can surely deflect this threat …”. Surely can …
…I have a dream. The industrial revolution and economic growth continue. This is because astrophysicists find a huge cosmic rock on course to hit Earth in 50 years. This should be scary enough. The world can surely deflect this threat but will need to develop new knowledge and technologies. Finally, in my dream, humans realise social media can make some people very rich but cannot save the planet. The latter requires new fundamental discoveries.
Men's hearts failing them for fear
25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
26 Men's hearts failing them (ἀποψυχόντων) for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.
27 And then shall they see the Son of man coming in a cloud with power and great glory.
Flaming sword, flashing, gave out flames
…at the left of Our Lady and a little above, we saw an Angel with a flaming sword in his left hand; flashing, it gave out flames that looked as though they would set the world on fire; but they died out in contact with the splendour that Our Lady radiated towards him from her right hand: pointing to the earth with his right hand, the Angel cried out in a loud voice: ‘Penance, Penance, Penance!’.
A punishment greater than the Deluge
…if men do not repent and better themselves, the Heavenly Father will inflict a great punishment on all humanity. It will definitely be a punishment greater than the Deluge, such as has never been seen before.
Fire will plunge from the sky and a large part of humanity will perish… The good as well as the bad will perish, sparing neither priests nor the faithful. The survivors will find themselves plunged into such terrible hardships that they will envy the dead. The only arms which will remain for you will be the Rosary and the sign left by My Son.
Each day recite the prayers of the Rosary. …
According to preliminary estimates the asteroid will pass through the Pacific and Central America. Monagua city, Nicaragua, San Jose in Costa Rica and Caracas are located exactly in this zone. But if the flight path is changed at least a few centimeters, the West Coast of America would be under attack as well. Apophis will fall into the ocean, forming a crater with depth of 3 km and a diameter of 8 km. Such a collision generates tsunami in all directions. As a result of it the California coast gets hit by a 20-meter waves, which are going to bombard the mainland for five days.
In addition to earthquakes, tsunamis and epidemics that will bring Apophis, powerful impact of the asteroid could change the Earth's axis of rotation. … During such a reversal the magnetosphere of the Earth for some time disappears and a cosmic ray flux falls to Earth. Such rays are very dangerous for the inhabitants of the planet. According to scientists namely a pole shift is responsible for the Deluge, Atlantis's disappearance, the sudden disappearence of dinosaurs and mammoths.
Scientists from NASA have calculated that since 2029, when Apophis falls into the Gravitational keyhole, humanity will not be able to avoid a collision. For this reason the US military space forces now are developing models of asteroid destruction.
The oceans will flood whole areas of the earth
Given the seriousness of the contents…
The Holy Father was asked, "What about the Third Secret of Fatima? Should it not have already been published by 1960?"
Pope John Paul II replied: "Given the seriousness of the contents, my predecessors in the Petrine office diplomatically preferred to postpone publication so as not to encourage the world power of Communism to make certain moves.
"On the other hand, it should be sufficient for all Christians to know this: if there is a message in which it is written that the oceans will flood whole areas of the earth, and that from one moment to the next millions of people will perish, truly the publication of such a message is no longer something to be so much desired."
9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
It is better not to worry…
Corresponding Member of the Russian Academy of Sciences, directing the
The mission "Aida" is able to work with a small asteroid. But what to do with such as, for example, the 350-meter Apophis threatening the Earth in 2029? Some experts believe: in the case of catastrophic danger we still have to throw on this asteroid the atomic bomb. So, we need to prepare now for such an invasion…
Boris Shustov: Let's see. One can speak with absolute certainty that in 2029 Apophis does not threaten Earth at all. With regard to 2036, and in general the foreseeable future, the probability of collision with it is negligible. But you're right — it is almost impossible to deflect large asteroids using the strike. And against very large (larger than 1 km) even the bombs are powerless. But the probability of collision with such giants is so scanty that to worry about it — just nothing but to poison your life. We earthlings have a lot of very real much more serious problems to deal with them today.
