Today, Saturday, November 20, 2021, the world will see a plane Asteroid The largest is called 2004 UE, and it attracts attention due to its size. At over 300 meters long and 140 meters wide, it is actually a large body.
The Jetta Astronomical Society also revealed in a statement that the asteroid is classified as “the closest object to Earth”, but since the asteroid travels less than 4 km, we need to know that the word “close” is relative. Million kilometers, which is about 11 times the distance between the Moon and here.
If an asteroid of this size approaches Earth in the future, NASA is preparing for it from now on. Later this November, a spacecraft called DART will be launched, which will crash into a distant asteroid in space – testing our ability to transform such rocks if anything approaches in the future.
Meanwhile, the asteroid passing through Saturn poses no danger, but a reminder that the universe is full of debris.
Asteroid is a rock that travels in space from the remnants of the formation of the solar system that scientists are studying, because it is an element that can know what the dawn of our solar system was like.
Most asteroids are found in the asteroid belt between Mars and Jupiter, and their orbits often intersect with Earth’s orbit.
NASA’s asteroid “close” to Earth is not by its distance from our planet, but by how far it is from the sun. Accuracy and their location will be known at any time.
A small percentage of these asteroids are “dangerous” – at least 152 meters wide, and within 7 million kilometers of Earth, most of these meteorites, passing on Saturday, pose little danger.
On Saturday the asteroid will not be visible to the naked eye because it is so far away, and the light reflected from it will be very dim, invisible even with most telescopes.
If an asteroid gets too close to our planet in the future, there is an intention to push it in a different direction before that. This is the mission of the spacecraft (DART) created for NASA by the Johns Hopkins Applied Physics Laboratory, and is scheduled to begin in late November, and ten months later, in September 2022, the spacecraft collides with an asteroid (Temarobos) at a speed of 23 kilometers per hour.
In general, according to NASA data, more than 100 tons of dust and sand – sized particles enter the Earth’s atmosphere daily without any effects, while a car – sized asteroid enters the Earth’s atmosphere once a year, but it burns and does. Before a magnificent fireball reaches the surface, but no threat.
