3 asteroids will fly past Earth on Saturday. Here's why there is no need to panic


Despite the headings like, "NASA Asteroid WARNING: The three giant asteroids that let the Earth THROUGH SATURDAY, "and" CLOSE THE APPROACH "of the NASA Asteroid as the three cosmic stones that move past the Earth on Saturday afternoon," there is absolutely no panic.

In fact, NASA did not warn or warn anyone about the dangers of asteroids.

It is true that the newly discovered asteroid will pass through the orbit of the moon, but it does not pose a threat to the Earth.

The 2018 VX1 asteroid was discovered by the telescope at Mount Lemmon Survey in Tucson, Ariz., November 4. The asteroid will pass around 381,000 kilometers of Earth. This is three kilometers closer than the average distance of the moon from our planet.

If it sounds close, consider this: all planets in our solar system, including Pluto, can fit in between Earth and the Moon. There is a lot of space.

So far, based on relatively limited observations 2018 VX1, astronomers have calculated that it is the nearest 11-meter rock that will come to Earth to 2110 (it has a period of circulation around the Sun for 1.6 years).

At 1:20 ET on Saturday, 2018, the VX1 will safely pass the Earth at around 20,000 km / h.

And although it may seem alarming that the asteroid is approaching so close to the Earth that it was discovered a few days earlier, it happens more often than it might seem. This is because asteroids are relatively small and therefore difficult to see.

But this is good news: they are small.

Hypothetically, if the 2018 VX1 were to enter the Earth's atmosphere at some point in the very distant future, it would be a nice light show and probably some sound, but without catastrophic injuries.

Putting this in perspective, the Chelyabinsk asteroid – also referred to as a meteor – crumbling over Russia in 2013. It had a diameter of 20 meters. The resulting air erupted when it entered the Earth's atmosphere, smashes windows, injures about 1,000 people. But Chelyabinsk it was almost twice as large as 2018 VX1.

If you want to watch 2018 VX1, when it passes, you can visit Virtual telescope project on Saturday for live view.

Two more guests

There are two more asteroids on Saturday.

Around 9.00 ET, 2018 VS1, which is approximately 17 meters wide, will whizz in around 38,000 km / h, over 1.3 million kilometers from Earth.

A 2018 VR1 will be more than five million kilometers from Earth, when it will pass by it at the same time.

So it's quite clear that you do not have to worry that any of these asteroids can be a threat to Earth.

But if the idea of ​​destroying the asteroid hitting the Earth will keep you at night, consider this: 95% of asteroids, one kilometer or more wide, are thought to have been discovered by sky research, such as NASA Center for research on objects close to the Earth.
