Huge asteroids are anxiously close to the Earth



Three asteroids-scammers are set at speeds that are inconveniently close to Earth tomorrow.

The largest of the three can lead to a catastrophe if it crashes into our planet, and is as large as the Pisa Tower.

This is stated in a NASA report that cited asteroids on the "Earth and Earth" alert page.

The first will pass Earth about 3:20 AM tomorrow (on Tuesday, January 15, at 2.20 AEDT) at a speed of more than three miles per second (17.380 km / h).

Known as the 2016 AT6, the 17-meter scroll slides in two million miles from the Earth, or about eight times the distance between our planet and the moon.

The second space rock that will fly past the Earth tomorrow, 2019 AM8, is much larger than its predecessor, and is approaching us twice as fast.

As big as a blue whale, it will hit a speed of almost seven miles per second (40.555km / h) as it passes the Earth on Tuesday at 4:03 pm (Wednesday, January 16, 3.03am AEDT).

The asteroid will pass our planet a little more than 2 million kilometers from its surface, or eight and a half times the distance between the Moon and Earth.

The third asteroid, which is scheduled for a close shave with the Earth, is AG9 2019 – and it is the largest party.

Measuring 51 meters in diameter means it's as wide as the Pisa Tower is tall – 2019 AG7 is planned to fly at 10:43 pm tomorrow night (Wednesday, November 16, 9.43 AEDT).

Attaining a speed of 4.2 miles per second (24,333 km / h), it will go closer than its predecessors, interlacing within 950,000 miles (1.53 million kilometers) of our planet – about four times the distance between Earth and The moon

It is expected that twelve near-Earth objects will fly past our planet now and by the end of this month, which means the tomorrow's trio is not unusual.

The good news is that astWeroids are actually classified as "small bodies" of NASA, which does not believe that the objects are a threat to life on Earth.

Even if they were on the way to collide with our planet, asteroids of this size often fall apart in our atmosphere long before they reach its surface.

"Global disasters" only work when more than 1000 meters in size crash into the Earth, NASA reports.

What is the difference between asteroid, meteor and comets?

Asteroid: The asteroid is a small rock body rotating around the Sun. Most of them are in the asteroid belt (between Mars and Jupiter), but they can be found anywhere (including in a way that can affect the Earth)

Meteoroid: When two asteroids are in contact with each other, small pieces that break up are called meteoroid

Meteor: If a meteoroid enters the Earth's atmosphere, it begins to evaporate, and then becomes a meteor. On Earth, it will look like a strip of light in the sky, because the stone burns

Meteorite: If the meteoroid does not evaporate completely and travels through the Earth's atmosphere, it can land on Earth. At this moment it becomes a meteorite

Comet: As the asteroids, the comet rotates around the Sun. However, the comet, instead of being made primarily of stone, contains a lot of ice and gas, which can lead to the formation of amazing tails (due to the evaporation of ice and dust)
