Too many are the asteroids approaching the Earth, which we know about some of them and we do not know about most of them, as they pass in peace and quiet. Their small sizes and vast dimensions prevent us from seeing them, or even noticing their presence in the sky.

Every day, scientists determine a list of the names of those asteroids coming from the asteroid belt between Mars and Jupiter, which take close orbits to Earth, give their coordinates and dimensions, and determine the extent of their danger to Earth.

The asteroid that will enter less than the distance of the moon from the Earth (384 thousand kilometers) is considered an asteroid that deserves constant monitoring and monitoring, for fear that its path will change due to the gravity of the planets or even the gravity of the Earth itself.

Solar System Guard

For example, Jupiter, which is the largest of the planets, works as a guard in the sky of such objects, especially those coming from the edges of the solar system, such as comets that pose a real threat to life on Earth.

Were it not for the great gravity of Jupiter that is deflecting the direction of the comets and changing their course, the Earth would be highly vulnerable to periodic collisions that pose a threat to it.

Therefore, scientists looking for smart life in the universe considered the presence of a large object such as Jupiter in the star group that is being searched for on a habitable planet such as Earth as a fundamental factor, as how would life be safe from the danger of such objects on a land that is supposed to be stable so that the form of life appears on it?

For example, about 66 million years ago, a comet or asteroid with a diameter of about 15 kilometers collided with the Earth, which caused a great disaster on the history of the Earth and the development of life in it, and because of it, 3 quarters of the life that was on Earth at that time became extinct, including the dinosaurs, those creatures. The great.

The average diameter of the asteroid that visits us is 30 meters, at a distance of a third between us and the moon, which is about 130 thousand kilometers (Hani Al-Dulaie)

The next asteroid

On the first of next September 2020, an asteroid with an average diameter of 30 meters at a distance of one-third between us and the moon, or about 130 thousand kilometers, will visit us, as it completes one revolution around the sun every 9.5 years, and the last time it was seen was in March 2011 .

This asteroid marked ES4 (2011 ES4) is one of 40 asteroids approaching Earth during the period from mid-August to mid-September next, and this indicates the large number of these bodies that were and are still crossing us without To pay attention to us, and without us paying attention to it in the past, but we have started to do so recently.

Exactly like the number of eclipses and eclipses that people think have increased in the modern era, while they did not, but the media that began searching for all events is the one that is emerging even the invisible ones, which are semi-shadow eclipses or the invisible eclipses in our regions.

But is this dangerous crossing? Could its path be deflected by Earth's gravity? Does the moon have an effect on its path as it will pass between us and the moon?

Not much history has been recorded since those events in which there was great destruction and damage to humans, until the modern era, even meteorites were only recorded in small numbers that directly hurt people, but they did not pose a real threat, so the last thing that fell on Earth was meteorite Russia in 2013, and did not Only hits the ground, but no casualties.

Because of the asteroid's smallness, its dim luminosity will not allow us to see it except through relatively large telescopes and from very dark areas (Hani Al-Dhale'e)

Will we see an asteroid?

The transit of the asteroid closest to Earth will be favorable to the continent of Asia, especially the eastern and southeastern regions, as the closest meeting will take place at 7:12 pm Mecca time in Sagittarius, near Jupiter, but because of its smallness, its faint brightness will not allow us Only seen through relatively large telescopes and from very dark areas.

The speed of its movement in the sky will reach 8.2 kilometers per second, and because it is very far away compared to satellites such as the International Space Station, which is traveling in the sky at almost the same speed, it moves very slowly, and if it is seen with a telescope, its movement will be noticeable between the stars.
