When a planet suddenly disappears from the solar system, how should humans deal with it?

Our solar system has been born for billions of years. After a long period of evolution, we have finally formed the solar system we know today. There are eight planets in the solar system, which are Mercury, Venus, earth, Mars, Jupiter, Saturn, Uranus and Neptune in order of distance from the sun. Each of these planets is in its own orbit under the sun’s gravity. So the question is, if one of the planets disappears from the solar system by accident, what will happen in the solar system? Will the earth be affected? Can human beings survive?

First of all, what happens when Mercury suddenly disappears?


Mercury is the closest planet to the sun and the smallest planet in the solar system. We all know that gravity is the key to any star in the universe. So when Mercury disappears, we’ll find that it doesn’t seem to have much impact on the entire solar system. In other words, if you have to remove a planet from the solar system, then the best choice is mercury.

What happens when Venus suddenly disappears from the solar system?

Venus is also known as the “Sister star” of the earth because its mass is similar to that of the earth. But in fact, it and the earth can only be regarded as “seemingly in harmony with each other.”. Compared with the earth’s strong magnetic field, Venus is the only planet in the solar system without a magnetic field.


Although Venus also has an atmosphere, more than 97% of it is carbon dioxide. Under the effect of greenhouse effect, Venus has become the hottest planet in the solar system. However, its disappearance will not cause too many ripples in the whole solar system. But because it is the brightest object in the night sky after the moon, the disappearance of Venus may make the earth’s night darker.

What happens when Mars suddenly disappears?


Mars is one of the most ordinary celestial bodies for human exploration. What will be the impact of losing Mars? Since the mass of Mars is only 11% of that of the earth, we don’t have to worry about the negative effects of gravity if we lose Mars. On the contrary, the loss of Mars seems to have another advantage for the earth, because there is an asteroid belt between Mars and Jupiter, which is bound by Jupiter’s gravity, and these asteroids are well fixed in their orbits.

However, these asteroids occasionally collide, resulting in orbit deviation. Coupled with the gravity of Mars, these asteroids will break away from the gravitational shackles of Jupiter and move towards the earth. In other words, without the interference of Mars, maybe our earth would be safer.

What happens when Jupiter suddenly disappears?


Jupiter is the largest planet in the solar system, and its mass is 2.5 times the total mass of the other seven planets in the solar system. This means that it has a strong gravity, so its status and influence are beyond doubt. Once Jupiter disappears, the asteroid belt between Jupiter and Mars will lose control and fly to another, the maximum gravity field they can reach.

There is no doubt that the largest gravitational field is the sun, and in this process, planets inside the sun, such as the earth, are bound to suffer accidental damage from asteroids. In addition, Jupiter’s strong gravity is also a stabilizer for the earth. Once the gravity of Jupiter is lost, the earth is likely to change its way around the earth. Therefore, the disappearance of Jupiter has the greatest impact in the entire solar system, and even directly affects the survival of human beings on earth.


What happens when Saturn suddenly disappears?

Saturn is the only planet with rings in the solar system and the second largest planet in the solar system. It belongs between Jupiter and Uranus. Therefore, the disappearance of Saturn will directly lead to the orbit deviation of Saturn and Uranus. But that’s all it has to do, because Saturn is so far away from other planets.

What happens when the star disappears suddenly?


Uranus is also the third largest planet in the solar system, so its disappearance will have a huge impact on Jupiter, Saturn and Neptune. But because of the distance, it has no effect on the first four planets, including the earth. Neptune is the farthest planet from the sun, because of its mass and distance, its disappearance will not have much impact on other planets in the solar system. But it is undeniable that its disappearance will cause great chaos to the Kuiper belt.

What happens when the earth suddenly disappears?


To be honest, the disappearance of the earth will not have much impact on the entire solar system. Because there is a sun in front of the earth and a Jupiter behind it, the gravitation of the two is enough to make up for the loss of the earth. However, in a sense, the disappearance of the earth may be the biggest loss to the solar system. Because no earth means no human civilization, it will be more boring for the solar system and even the whole universe.
