Why not hit Mars with an asteroid to bring it closer to Earth?

First of all, the asteroid is not under our control, and if the asteroid hits Mars, it may not bring it closer to the Earth.

Because the gravitational force between the Earth and Mars is relatively large, it cannot be changed by an asteroid.

Since the discovery of the underground liquid lake on Mars, humanity's enthusiasm for Martian immigration has increased. However, due to the distance between Mars and the Earth, it generally takes 100-300 days to reach it by a modern vehicle.

According to scientists, this conjecture could theoretically be realized, with Mars being the fourth planet in the solar system from the inside out, reaching the Earth at a distance of 55 million kilometers at its closest point and more than 400 million kilometers at its farthest distance. With the gradual discovery of Mars exploration, scientists believe that Mars is very suitable for human migration, and various space agencies have also carried out research on landing on Mars. Scientists have then conducted simulated impact experiments by changing the orbit of an asteroid to make it hit Mars, bringing Mars closer to Earth, which will reduce the time of our interstellar journey.

Scientists have found that at least 3 to 7 collisions are needed to deflect Mars from orbit, but there will be a huge **, and some of the material on Mars will also be shattered by the collision.

Moreover, some scientists believe that there is no technology that can re-change the orbit of the asteroid so that it will hit Mars in a directional direction without offset, and even if it can really hit Mars, there is no certainty that Mars will definitely deviate its orbit.

How much ** and tribulation the universe has gone through to get to its current state. You still want it to bump into it. That doesn't break the rules of the game in nature, sometimes I always feel that we humans are like artificial intelligence, it's just a microparticle, a certain part of the cell, too small.

When Jupiter formed, the protoplanetary disk had not yet dissipated. Jupiter exchanges angular momentum with the protoplanetary disk, loses mechanical energy, and spirals towards the Sun. Subsequently, Saturn developed and formed 2:

The orbital resonance of 3 prevents Jupiter's inward migration, and the two turn outward together under the action of the inner lindabo resonance. This process causes stars within an astronomical unit region to be driven away by gravitational slingshots, and some of them go closer to the Sun, thus making a deal between Earth and Venus.

As a result, Mars is "malnourished", while terrestrial planets cannot form outside of Mars, leaving only a few asteroids. All it takes is a small telescope for us to appreciate the heroic gesture of the King of the Planets – its distinctive orange color and cascading clouds. With a slightly larger telescope, you can see the famous Great Red Spot on Jupiter's surface.

However, it is important to note that because Jupiter rotates very fast – it can rotate once in less than 10 hours – when we see the Great Red Spot on Jupiter's surface, it may have turned to the backside. <>

This rapid rotational speed also makes Jupiter's equatorial region significantly fatter than its polar region. The average distance from Jupiter to the Sun is 100 million kilometers, and it takes almost 12 years to complete one revolution. Jupiter's composition is about the same as that of the Sun – 75% hydrogen and 24% helium.

However, we still don't know what's going on beneath Jupiter's surface. Some people think that Jupiter has a dense core, but we don't know how big this core will be. <>

Astronomers also believe that there is a layer of liquid hydrogen between Jupiter's core region and the outer atmosphere, and that cloud bands in the middle atmosphere tend to move in the opposite direction of rotation. Some dark areas are called "strips" and some bright areas are called "strips". The lightning detected there is 1,000 times stronger than on Earth, and the Great Red Spot in Jupiter's Southern Hemisphere cloud belt is a huge anticyclone that has existed for a long time.

It used to be the size of four Earths, but recent observations suggest it's getting smaller. <>

It's possible. The small bodies of the solar system revolve around the Sun in elliptical orbits. If the main belt asteroids collide, the elliptical orbit cannot remain intact.

If some asteroids are too close to a large planet in orbit, they will also be subject to strong gravitational perturbations, and factors such as their coordinates, velocity, or orbit will also change. In this case, they are likely to be captured by the asteroid and become the moons of the asteroid, or they may be thrown out of the solar system, or they may crash into the Earth.

In the solar system, the eight planets orbit in an elliptical orbit with the sun as the center, and the fundamental reason for this is the action of force. For example, there is a gravitational attraction between the sun and the earth. This force doesn't have much effect on the sun, but it's enough to suck the earth to the sun.

The reason why the earth is not sucked away by the sun is that when it rotates around the sun, it forms a centrifugal force, which is added together with its own gravitational force to reach a balance with the gravitational pull of the sun. As a result, the Earth can revolve steadily around the Sun for hundreds of millions of years.

As small bodies of the solar system with a more inconspicuous mass and volume, most of them revolve around the Sun in elliptical orbits, just like the eight planets. But not all small bodies will always follow the rules of an elliptical orbit, and if the main belt asteroids collide, the elliptical orbit will not remain the same. If some asteroids are too close to a large planet in orbit, they will also be subject to strong gravitational perturbations, and factors such as their coordinates, velocity, or orbit will also change.

In this case, they are likely to be captured by the asteroid and become the moons of the asteroid, or even thrown into a parabola or hyperbolic orbit centered on the Sun and finally fly out of the solar system.

If an asteroid deviates from its orbit, it is likely to upset the original balance and crash into Earth.

Because an asteroid hit the earth, it caused the dinosaurs to go extinct.

In 1980, Nobel laureate in physics Louis Alvarez, his sons Walter Alvarets, Frank Asaro, Helen Michel and others found that the global Cretaceous and Paleogene strata had higher levels of iridium than normal.

For example, the iridium content of the two formations in the original study was 30 times and 130 times the normal standard, respectively. Iridium is a very rare metal in the earth's crust and is an ironphilic element.

Most of the ferrophilic elements settle into the Earth's core, such as iron, during the planetary differentiation. Since iridium is often found in most asteroids and comets, Alvarez et al. believe that an asteroid hit the Earth's surface at the beginning of the Cretaceous and Paleogene periods.

Dinosaur development history:

Dinosaurs flourished in the Mesozoic Era, dominating for a while, and the earth became a world of "dragons". For example, the winged dragon flying in the air, the forelimbs become flying organs, the ichthyosaur that lives in the water, the Lufeng dragon that lives on land or in the swamp, and the Hechuan Mamenxi dragon are all typical representatives. Non-avian dinosaurs lived on Earth for hundreds of millions of years, and a branch of theropod dinosaurs branched off into birds, but at the end of the Cretaceous period, they suddenly disappeared from all parts of the world.

This is due to the strong orogeny, changes in topography, climate and food shortages, etc., the ancient reptiles, dinosaurs, which dominated the earth for more than 100 million years, were completely extinct at the end of the Mesozoic Era.

A wandering planet the size of Mars 4.5 billion years ago caused the largest impact in Earth's history. The wandering planet, named Ternia, rushed towards the Earth at a very high speed and crashed straight into the surface of the Earth. The impact caused great destruction.

The planet Ternia cut through the Earth's crust, which carried the Earth's crust into space, and the debris from the impact was gravitationally pulled, eventually forming the current Moon. The impact caused a devastating catastrophe on Earth, but it also brought our Earth full of carbon, nitrogen, and sulfur needed for life, and humanity and other life on Earth might not exist without this impact.

Speaking of which, there is a planet the size of Mars that is about to hit the Earth, what will happen to the Earth? In the weeks leading up to the impact, an unknown object appeared in the sky. The news will report that the planet is about to hit humanity, knowing what is going to happen, but there is nothing that can be done.

As we will see, the planet gradually grows larger, until one day, when it is as big as the moon, and it seems that everything is tense but unusually slow. But that's only because it's too far away.

In space, wandering planets will rush towards us at a speed of 11 kilometers per second and hit the Earth. Two days ago, the planets will enter the orbit of the Moon, disasters will begin to occur, the gravitational pull of the wandering planets will increase the tidal force on Earth by eight times, floods will sweep the coastline, and the giant tsunami of the city is yet to come. 28 hours before impact, the gravitational pull of the two planets will be closer, and the collision will accelerate with each other, and the intrusive planet will hit at a speed of 60 kilometers per second.

A giant tsunami will erupt over the ocean, and most of the land will be engulfed by the tsunami, followed by a lightning storm. They will wreak havoc across the globe.

Those who do not board the spaceship will face death.

Three minutes before the impact, the wandering planet entered the Earth's atmosphere. If you still survive, you'll see planets fill the sky above, crashing into the atmosphere of the two planets in an instant that will glow brightly. The heat will cause one side of the Earth to evaporate immediately, and the ground will be scorching magma and collide, causing the two planets to rub against millions of tons of superheated rock, sending a wall of fire in all directions.

The inner core of the Earth will melt from the inside out, and the Earth will collapse on its own, which is the day of humanity's demise.

At this point, humans who have managed to escape into the spaceship will see a large amount of remnants of the two planets floating in the air.

Some of them will continue to attack other planets, and some will fly out of the solar system. An asteroid belt will form around the Sun. At this time, there is no evidence that intelligent life ever existed on Earth.
