The near-destruction: Asteroids

The destructive object, as you must have seen in different sci-fi movies, it is even forecasted that it might destroy the planet Earth. There were several discussions about the asteroids that are near, and we’ve finished along with this pandemic. Hopefully, there weren’t such incidents. 30th June, the world celebrates this day as World Asteroid Day. Let us know why.

The day after the declaration by UN General Assembly in December 2016, now it will be observed every year as a remembrance to the Tunguska impact in Siberia, presently Russia, in the year 1908. The effect was so powerful by flattening over 2000 sq.km area. The trees fell all over the village; it was a spark all of a sudden, and a loud sound filled in the nearby area equivalent to giant bomb detonated, but this is by nature itself.

Asteroids, sometimes described as minor planets and some are called planetoids when they’re more substantial in size. Ceres, being the first asteroid noticed in 1801 by Giuseppe Piazzi, was discovered as a planet. Sir William Herschel, an astronomer, coined the term asteroid. Most of them found in the orbit of Mars and Jupiter. Even you might have heard about the Kuiper belt, the home to three dwarf planets, including the Pluto. It is similar to the asteroid belt.

Few asteroids are more than 100 km in diameter, which can be a threat, but hardly an asteroid hits the Earth so massively once in 2000 years or more. There is a possibility that the dinosaurs could have wiped away due to a colossal asteroid. The thing to consider is that comet, meteoroid, meteor, and meteorite aren’t the same. Hence, you might know a meteor is also a shooting star, which is said to fulfill your wishes when you see it up in the sky.

These NEOs or near-Earth objects can be a significant threat, although many small objects hit the Earth daily. According to an estimate, almost 17 meteors every day, and this can increase in the future exponentially. If you saw the movie, Ice Age: Collision Course, the film has a scene where an asteroid hit Earth. There are almost more than 600 thousand asteroids present in the space. The first asteroid, as described, did an explosion occurs at an altitude of around 5-10 kilometers, which resulted in wiping out 80 million trees and a glow spread about far from 700 kilometers. The sound could be audible from a thousand kilometers from the origin.

The most massive asteroid has a diameter of 900-1000 kilometers, with a mass equivalent to 32 percent of the entire belt between Mars and Jupiter. One of the documentaries by W.D. Hogan can release in the theaters on 8th October 2020. It has explanations about the origin, what risks can get involved, and how can we save against them. Luckily, the first asteroid fell in a barren land. If it were a living habitat, a lot of people would lose their life; they’ll have almost no time to escape. Prepare well in time, and sometimes the rumors may also turn true.
