When does the Emergencies Ministry predict the approach of the asteroid Apophis to the Earth?

The dangerous asteroid Apophis will fly up to Earth on April 13, 2029. This was reported at the All-Russian Research Institute for Civil Defense and Emergencies (VNII GOChS).

According to calculations, the space object will approach the Earth by almost 38.4 thousand kilometers. This is almost the same distance at which geostationary satellites are placed in orbit.

What will happen when Apophis approaches the Earth? & nbsp;

According to VNII specialists, the speed of approach of Apophis to the Earth will be 7.42 kilometers per second. The energy that will be released in a possible collision of an asteroid with a planet will amount to 1,717 megatons, which is 30 times more than the explosion of the world's most powerful Soviet thermonuclear bomb, which was tested in 1961.

within a radius of 10 km from the place of fall, it can reach 6.5 points on the Richter scale, the wind speed will be at least 790 m per second '', & mdash; said in the forecast of the institute.

What is known about the asteroid? & nbsp;

The asteroid Apophis was discovered in 2004 by Roy Tucker , David Tholen and Fabrisio Bernardi at the Kitt Peak Astronomical Observatory in Arizona, USA. The near-Earth asteroid belongs to the Aton group ( a group of near-Earth asteroids whose orbits intersect the Earth's orbit from the inside & mdash; approx. ed .).

Originally an asteroid was called 2004 MN4, but in 2005 it was named Apophis in honor of the ancient Egyptian evil demon Apophis (Apep, Apophis, Greek Ἀ & pi; ό & phi; iota; & sigmaf;).

In ancient Egyptian mythology, Apopis & mdash; it is a giant serpent that lives underground, the personification of evil, darkness and chaos. The Egyptians believed that every night the sun god Ra fought Apophis when he embarked on a journey along the Nile River. & Nbsp;

What is the probability of Apophis colliding with the Earth?

According to scientists, despite the fact that Apophis will fly close to Earth, it will not fall on our planet. Initially, the probability of its collision with the Earth on April 13, 2029 was estimated at 2.7%, but later it was completely ruled out. & Nbsp;

According to experts at the University of Hawaii, the asteroid annually deviates from its orbit. The reason & mdash; The sun unevenly heats the surface of a space body, which is why it receives a weak reactive impulse due to thermal radiation from the side warmed up during the day. According to Dave Tholen of the University of Hawaii Institute of Astronomy, the asteroid is observed to be moving away from its gravitational orbit by about 170 meters per year.

Earlier it was expected that on April 13, 2029, a celestial body will pass at a distance of 29,470 kilometers from the Earth. & Nbsp;

In NASA, Apophis is called one of the most dangerous asteroids for Earth. It was originally thought to be dangerously close to Earth in 2029 and 2036. Later, these predictions were refuted. In March 2021, refined calculations showed that the likelihood of a collision of Apophis with the Earth in 2068 is also minimized and that there is no risk, at least for the next 100 years.

What other asteroids are approaching the Earth? & Nbsp;

Earlier, the British tabloid The Sun, citing NASA data, reported that two potentially dangerous asteroids are approaching the Earth. According to the publication, one of them & mdash; 2013 YD48 & mdash; the size of Big Ben. The asteroid is about 104 meters wide and will pass the planet on January 11 at a distance of 5.6 million kilometers. The second celestial body & mdash; 7482 YD48 & mdash; twice the size of the American Empire State Building, the asteroid will approach Earth on January 18. It will be separated from the planet by about 2 million kilometers. & Nbsp;

According to NASA Deputy Head Thomas Zurbuchen , none of the asteroids currently known to science poses a threat to our planets in the next hundred years.
