Asteroid Near Miss: This would happen if an asteroid would hit Earth Science | news



An enormous asteroid about the size of a football field flew over the earth last month and hit astronomers who did not know it. The incident was all the more serious when the space rock passed the earth in 2019 at a distance of 65,000 km (40,400 miles) – only a fifth of the distance to the moon. Although it is extremely unlikely that an Apocalypse asteroid will occur soon, it could one day hit Earth.

The damage an asteroid can cause on Earth depends on three factors: its size, speed and composition.

The composition of an asteroid is mainly determined by its proximity to the sun.

Those closest to the Sun are mostly carbon, while those further away are silicate rocks.

Even modest asteroids storming down from the sky will boast much of energy.

If an asteroid the size of a house hit the earth at a speed of 4800 km / h, it would a lot of energy is about the size of the 20-kilo-ton bomb that destroyed Hiroshima.

Such an asteroid could flatten reinforced concrete buildings to a distance of 0.8 km from zero and severely damage any city.

An asteroid the size of a 2 A 0-storey building (200 feet) has an energy equivalent to that of the largest atomic bombs made today ̵

1; up to 50 megatons.

Such a space rock would flatten reinforced concrete buildings even five miles (eight kilometers) from zero.

This could consequently wipe out most of the larger US cities.

Even kilometer-wide asteroids are known to exist, which have the destructive power of 1 million megatonnes atomic bombs.

This is the energy 10 million times higher than the bomb that leveled Hiroshima.

It is able to plate everything for 100 to 200 miles from Ground Zero.

If a kilometer-wide asteroid hits London directly, it would destroy everything in Brussels and Amsterdam and cause a great deal of damage, perhaps 1,000 mi les out – that's as far away as Sarajevo and Naples.

The amount of dust and debris thrown into the atmosphere would block sunlight and kill most living things on Earth.

If an asteroid of this size landed In the ocean, it would trigger tidal waves several hundred meters high that would completely eradicate the nearby coasts.

In the year 2028, the asteroid 1997XF11 will come dangerously close to Earth but miss the planet.

If something happened, it would change and hit Earth, the miles-wide asteroid would hit Earth at a speed of 30,000 miles per hour.
