Our Earth orbits with other objects in the Solar System. Among these celestial bodies, there is an object that is called threatening the Earth. The sizes also vary. How dangerous is this object threat?
There are indeed those who observe NEOs (Near-Earth Objects) or near-Earth objects, generally asteroids or comets whose orbits are close to Earth.
So actually objects in this Solar System have planets, asteroids, maybe also rocks called meteoroids or even meteors, both of which orbit the Sun.
One day, there will be objects whose orbits pass through Earth. It is at times like this that we often hear news or warnings that there are celestial objects of a certain size crossing our Earth. Is it dangerous?
Generally, until now and also estimated for the next 100 years, there are no objects that threaten the Earth.
He said some near-Earth objects are the size of a bus, but are farther away from the Earth-Moon. There is also an even bigger one, about the size of a football field. But even then the distance is still far from the Earth-Moon distance so it is safe.
So news of an asteroid approaching Earth or a comet passing near Earth is considered more of an astronomical interest to study more closely about the asteroid. The physical meaning and physical characteristics of the object are interesting to study, but there is no significant impact or even considered an impact that is harmful to the Earth.
Do not panic!
Djamal gave an example that last year a Planetary Defense Conference (PDC) was held in Vienna, Austria which simulated an asteroid hitting Earth. Many mistakenly think that this is the real threat of asteroid 2021.
The news is a simulation but in various media it seems as if there is an asteroid threatening Earth.
It was simulated in Europe, what if there was an object threatening Earth. How is the readiness of the relevant institutions, what is the scenario if it falls to Earth, what is the evacuation of its citizens like.
Therefore, we are reminded not to swallow such information, which can cause concern and even panic.
So we also have to be careful, we have to be able to choose and sort out the correct information. (Is) it's just a kind of simulation or even hoax news.
