Impacts can destroy a planet

Strong collisions with other celestial bodies or certain external influences can cause a planet to crumble.

The composition of the Earth includes: iron, nickel, magnesium, silicon and other elements. They are quite stable so we don't need to worry that Earth will suddenly explode. Other planets are not like that.

Jupiter is a giant gas planet composed primarily of hydrogen. Hydrogen can be very flammable when combined with oxygen and an energy source such as fire. This reaction produces a bit of water but also causes a big explosion.

If an alien army finds a suitable way to put in large amounts of oxygen, they can create a massive explosion that destroys Jupiter.

Strong collisions with asteroids can cause the Earth to be destroyed.

How else could a planet be destroyed? It is a very strong collision with asteroids.

Scientists believe that the Chicxulub asteroid that crashed into Earth 65 million years ago led to the extinction of the dinosaurs, the asteroid landing in what is now the Yucatan Peninsula, Mexico and leaving a pit big, but it's not enough to destroy the Earth.

This asteroid has a diameter of about 9km and rushes towards Earth at a speed of 64,000km / h. With such power, it still only created a 20km deep pit.

Large, denser asteroids or other constituents may collide strong enough to destroy the Earth. However, it is unclear what characteristics asteroids need to be able to destroy the Earth.

If colliding with asteroids can cause the Earth to be wiped out, what will happen if you hit another planet? Strangely, in some cases, the two planets collide will not crumble.

If one of the planets is young and is in its infancy, they can merge into one giant planet. Some scientists think that is what happens when the Earth collides with very young Theia planet about 4.5 billion years ago.

According to a study by the University of California, Davis, when two planets actually collided, they could produce synestia , a ring-shaped cloud of evaporated rocks. They will keep this state for several hundred years, very short compared to the time in the universe, then shrink, cool and form a new planet.

You may think that the Solar System has formed stable, so Earth will never collide with another planet. However, this may not be true.

In 2008, astronomers observed the star system of an age equivalent to the Sun and only 300 light-years from Earth. They found two planets colliding with very strong forces, causing a complete extinction event if any life form existed on it.

Prior to this discovery, the scientists had argued that star systems that lasted as long as the Solar System would avoid such a collision, but this seems to be inaccurate.

Apocalyptic apocalyptic scenarios are easy to bring about pessimistic feelings. However, these events are almost impossible in our time. So enjoy life on Earth, the roof of people.
