No one knew. A giant asteroid passed close to Earth

A giant asteroid the size of a 32-story building passed close to Earth last week. None of the world’s leading astronomical, astronomical, and astronomical observatories, including NASA, have been able to detect it. It could not be detected by intense sunlight.

The asteroid passed half the distance between the Earth and the Moon above ground level. Its trajectory was over Greenland and Canada. This is the second time this month that such an asteroid has passed. On September 7, astronomers in Arizona noticed an asteroid 2021 RS2 passing in the same direction. It was only when they got closer that they could see it. It was a small asteroid that would not have caused much damage even if it had landed on Earth.

But this will not be the case with the 2021 SG. If this asteroid, which is huge and has a speed of 90,000 kilometers per hour, had landed on Earth, it would have been a catastrophe.

In 2013, an asteroid (suspected to be a meteorite) crashed in Chelyabinsk, Russia, and several people were hospitalized due to the energy waves it emitted. But these are just minor accidents.

We have seen many types of natural disasters. But asteroids may not have seen the dangers of landing on Earth. We also know that the dinosaurs completely disappeared from the earth due to the impact and subsequent phenomena of an asteroid that hit the earth six and a half billion years ago.

The impact of multiple asteroids on Earth can be seen from the depths of large craters in many places.

Assuming that the number of asteroid falls is low during the time we are living in, it cannot be said that this will never happen. Each year, a number of small and large asteroids pass close to Earth’s orbit.

NASA and other astronomical organizations have set up telescopic systems around the world to monitor asteroids and take immediate, strong action. Even so, owning one is still beyond the reach of the average person.

As a solution to this, NASA is preparing some powerful systems. One of these is the Near Earth Object Surveyor Space Telescope. Launched in 2026, it will be able to monitor emerging asteroids and rocks. Dart is the latter. Dart is a spacecraft that aims to knock down an asteroid and launch it out of its orbit. It is about the size of a fridge and is driven by xenon energy.

Dart is orbiting Didymus, the closest asteroid to Earth, Didymus. Dart will jump at Didymus at 6.6 kilometers per second. Then it will jump and be a single thunder. NASA has not said for sure what will happen next. Sometimes the dart will be destroyed and the asteroid will do nothing. Sometimes the asteroid will go farther away from the earth due to the impact of the thunder. If that happens, it’s a hope. In the future, if any terrorist asteroid comes looking for us, we hope to have a weapon in hand to fight back.
