Can a planet hit the Earth? Why do planets hit the Earth?

Since ancient times, mankind has been deeply worried about whether other planets will collide with the earth and bring devastating disasters to mankind, and this worry has not been completely eliminated until now.

At the beginning of 1968, Professor Batra of the University of Sydney in Australia predicted that on June 15, 1968, the Asteroid Icarus would enter the Earth if it deviated slightly from its orbit, and it would smash large cities at a speed of 9 kilometers per second. Dr. Jackson of the University of California supports this view, saying that it is very likely. They calculated that if the planet Icarus collided with Earth, it could cause a large crater on land with a diameter of 1,000 kilometers; If it falls into the sea, it will cause waves up to 600 meters high, and thousands of cities and villages will be submerged; Even if it sweeps over the ground, the damage caused is no less than a disaster of a large ** or tornado, and even a ** mountain eruption.

This prophecy shocked the world and caused great panic in the world.

But Soviet scientists pointed out that this calculation was wrong, and the probability of a collision was zero. Sure enough, on June 15, 1968, Icarus "passed by" the Earth.

In 1978, an astronomer calculated that a "geographic asteroid" would collide with Earth in 1995. But calculations by Chinese astronomers show that in 1995 the "geographic asteroid" was four to five million kilometers away from Earth, so there was no need to worry. As it turned out, this was the case.

Scientific studies have shown that there are 5,200 asteroids in the solar system, most of which pass between Jupiter and Mars, and more than 200 of them may enter the Earth's orbit. In addition, there are comets that are close to the Earth, and these objects are called near-Earth objects. Calculations show that an asteroid with a diameter of 1,000 meters has the opportunity to enter the atmosphere about once every 30 years, and an asteroid with a diameter of 9 meters hits the earth with a destructive power no less than an atomic bomb, and an asteroid with a diameter of 1,000 meters hits the earth with a destructive power equivalent to the power of 100,000 megaton bombs.

Planets hitting the Earth is a natural phenomenon.

There are a large number of planets and asteroids in the universe, and their orbits may intersect with the Earth's orbit because their motion is influenced by many factors, such as gravitational interactions, planet-asteroid interactions, the evolution of planetary systems, and so on.

As a result, the orbits of some planets and asteroids may change, causing them to cross the Earth's orbit.

So. What is the gravitational interaction between the Earth and the planets?

There is a force of mutual attraction between the Earth and other planets, and this force is caused by the mass between the planets. According to Newton's law of gravitation, there is a gravitational force between any two objects, and its size is directly proportional to the distance between the two objects, the mass of the object, and the square of the distance.

What is the interaction between planets and asteroids?

Interaction refers to the state of motion of an asteroid under the influence of the planet's gravity.

The gravitational pull of the planet can have an effect on the trajectory of the asteroid, which changes the trajectory of the asteroid. This effect may cause the asteroid's orbit to change or even impact the planet.

Whereas, the evolution of a planetary system refers to the changes that occur in a planetary system over time due to the influence of various physical factors.

These factors include the gravitational interactions between the planets, the distribution of matter within the planetary system, the history of the formation of the planetary system, and more.

The evolution of planetary systems may lead to changes in the orbits of the planets, changes in the distribution of the number and mass of planets, and possible planetary impact events.

In conclusion, the gravitational interaction between the Earth and the planets and the interaction between the planets and asteroids are very important forces in the planetary system. The evolution of planetary systems can have a profound impact on the orbits of planets and the structure of planetary systems. For studying the formation, evolution, and impact of planetary systems, we need to understand the role and impact of these forces.
