The Covid-19 has already taken the world by storm. With more and more things affecting us daily, we are going to face asteroids too. Recent asteroid news tells us that there can be a collision on the 7th of June at 12:30 pm IST.
Several asteroids are said to hit earth this week but, the biggest one is the ‘163348 (2002 NN4)’, having a diameter of around 250 to 570 meters (820 feet to 1870 feet). Nasa has predicted that the asteroid would travel at a speed of 5.1 million kilometers.
The chances of getting hit by an asteroid are bleak. This type of occurrence has a one in 100 chance of hitting Earth every 100 years.
But, to have a better understanding on asteroids, let us dive in further.
What are they
As defined by NASA- ” Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets.”
The asteroids are usually present in the asteroid belt. The asteroid belt is home to million differently shaped asteroids.
The asteroids are said to be formed 4.6 billion years ago. Asteroids differ in shapes and sizes. They can be of great help to understand the history of planets.
The first asteroid to be discovered was the ‘Ceres’ which at first was called a planet but later was named an asteroid.
Types of Asteroids
There are three major types of asteroids and a total of five types.
- Dark C – These are made up of Carbon and are known as Carbonaceous asteroids. And, are said to be closer to the Sun.
- Bright S- They are preset closer to Mars and are made up of silicates. Are known to be somewhat metallic.
- Bright M– Known to be in the middle of the asteroid belt have a composition of metallic iron.
- D type– Closer to Jupiter is made up of dark carbonaceous material.
- V type– Are said to be present in the orbits of Jupiter and Uranus.
Effects of asteroids hitting earth
While the chances of asteroids hitting earth are very few, the effects are devastating. An impact by an asteroid is said to create a nuclear winter filling the earth’s atmosphere in the dust. It can also cause earthquakes, rumbling, or tsunamis.
Once the asteroid hits the Earth’s orbit it is called a meteor.
In 2013, the meteor that hit the Russian city Chelyabinsk injured 1200 people, creating a panic. The explosion generated a bright flash as it exploded at a height of 26.7 km. The light from the meteor was said to be brighter than the sun. There was an extreme heat faced by some people.
These balls of dust can wipe out an entire city or the entire human extinction.
The dinosaurs are said to have gone extinct because of the asteroid turned meteor Chicxulub. Chicxuclub has said to have wiped out 75 percent of the human race too. This is said to have happened 66 million years ago.
Other famous meteors are the Tunguska, Vredefort, Morokweng, and Allan hills 84001.
So, even if the chances are less, the repercussion can cause a lot of trouble. It can also be the end of the extinction of the human race.
Evolution has said to have formed after this very collision of asteroids, planets, and various other planetary objects.
With already so many things happening on the Earth, from cyclones to a pandemic, we have a lot on our plate. And, the asteroid has a very rare probability to hit us should be least of our concerns.
If it hits us, we are in to make history. 2020 will be the year that will be known for the most disastrous year for the Human Kind.
