If one of the planets moving around the sun disappears, will the harmony of the solar system be broken?
About 4.6 billion years ago, the gravitational collapse of a giant interstellar molecular cloud gave rise to the present-day solar system. The eight planets of the solar system and other celestial bodies are all centered on the sun and revolve around it. All these seem to be so perfect and harmonious. Have you ever thought that if the solar system loses a planet, this harmony will be broken? ? What will the earth face?
The eight planets in order of distance from the sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
What would happen if the closest planet, Mercury, disappeared?
First of all, it is certain that the solar system will not change much, because under the action of universal gravitation, all objects with mass have gravitational force and can attract other objects. If the mass of an object is greater, its gravitational force will be greater.
As the smallest planet among the eight planets in the solar system, Mercury has a radius of only 2439.7 kilometers at the equator, which is even smaller than some huge natural satellites, and its mass and gravity are also small. There is no gravitational extrusion effect inside, so in space The gravitational force is not great.
What would happen if Venus disappeared?
After talking about Mercury, let's look at Venus again. Venus is the hottest planet in the solar system. A Venus day is equivalent to 117 Earth days. If Venus disappears, the result will still be the same. The solar system will not stop because of it, and everything will remain the same, except for the earth. Without Venus, Earth would lose an object that illuminates the night sky, and the sky would be much darker after the sun goes down, because Venus is the brightest object after the moon.
What would happen if the earth disappeared?
The earth is not only a floating rock in the habitable zone of the solar system, it is also pregnant with all kinds of life, full of vitality. If the earth disappeared, then we would cease to exist, let alone talk about these hypotheses like we do now.
What would happen if Mars disappeared?
Mars is a planet that we yearn for very much. It is full of unknowns and mysteries. In recent years, scientists have also focused on researching it, sending probes to it, and looking forward to landing on this red planet one day. If Mars disappears, there will be no major changes in the solar system. But for Earth, it might be a good thing.
Why do you say that? Because there is a huge asteroid belt before Mars and Jupiter, these asteroids are not friendly to the earth, Jupiter will use its own strong gravity to gather asteroids around itself, but sometimes they will break away from Jupiter’s gravity, Moving in the direction of the sun, under the strong gravitational force of the sun and Mars, the speed of asteroids moving towards the earth will be accelerated, and the earth will also be "attacked" by these asteroids. If Mars were gone, then we would be far less likely to be attacked.
What would happen if Jupiter disappeared?
Jupiter is the largest planet in the solar system, and its mass is 2.5 times that of the other planets in the solar system combined. For the past 4.5 billion years, Jupiter has used its powerful gravitational pull to protect Earth from being hit by asteroids and other space junk. If Jupiter disappears, then the earth will lose the protection of its "big brother", and perhaps it will end up like the surface of the moon in the end.
What would happen if Saturn disappeared?
Saturn has beautiful Saturn rings. Scientists believe that the Saturn rings may be "eaten" by Saturn's huge gravity in 300 million years. Fortunately, we can still appreciate them now. If Saturn disappears, it may have certain consequences for the solar system, such as moving the orbit of Uranus, etc. After all, it is the second largest planet in the solar system.
What would happen if Uranus disappeared?
Uranus is the third largest planet in the solar system. If Uranus disappears, the result of Saturn should be similar. Galaxies that are too far away from it will not be affected, but the surrounding planets may not be.
What would happen if Neptune disappeared?
Neptune is close to the edge of the solar system, and there is a doughnut-shaped region beyond Neptune-the Kuiper belt. In this region, there are icy objects and many dwarf planets like Pluto.
If Neptune disappeared, the Kuiper belt would be a mess, because without Neptune's gravitational influence, the objects would not be able to remain stable, the orbits of the objects would intersect, and the objects would be smashing into each other. But for the earth, it will not be affected by it, because the distance between them is too far.
