Before mankind entered the age of technology, we would not think about many daily phenomena in this world. As for the phenomena that we can’t understand, the ancients gave them to the gods. For example, natural phenomena such as wind, rain, thunder and lightning were not understood by the ancients, so they imagined the god of wind, rain, thunder and so on.
In addition to these natural phenomena, the ancients would not think about the walking and jumping in our daily lives. For example, why do we only jump up to a height of tens of centimeters and then land? Why can’t you jump a few meters, dozens of meters away? In the eyes of the ancients, there was no concept of universal gravitation. It was a normal thing that we would fall when we jumped up, and there were no rules behind it.
But hundreds of years ago, a wise man appeared. He began to think about the mystery behind these things that were normal in the eyes of ordinary people. This wise man was the great scientist Newton. Newton discovered the truth behind the normal phenomenon of an apple landing, that is, the law of universal gravitation.
After the discovery of the law of universal gravitation, many phenomena in nature, including the universe, can be well explained. At this time, we still don’t know much about the outer space of the earth. It is not until human beings have stepped out of the earth with the help of science and technology that we understand that the place where humans live is only the surface of the earth.
Standing in space and looking at the living conditions of humans, you will find that humans are actually “hanging” on the surface of the earth. We can stand firmly on the surface of the earth without floating in the air because the gravity of the earth binds us. Under the action of gravity, we can only run about 50 centimeters on the earth.
The gravity of the planet affects how high a person can run. When humans take off on different galaxies in the solar system, how high they can run, we will follow the fantasy spaceship to start this adventure step by step.
We first came to Mercury, the planet closest to the sun. Mercury is the planet with the smallest mass in the solar system, and its low mass gravity is naturally very small. When you stand on the surface of Mercury and jump upwards, you can jump up to about 1.2 meters high. This kind of in-situ jump of 1.2 meters can easily break the world record on Earth.
We left Mercury, and the next stop is Venus. Venus is known as the sister planet of the earth, and its mass and volume are very close to the earth. Although it is the sister planet of the earth, the environment of the two is very different. If the earth is heaven, then Venus is hell.
Venus has the strongest greenhouse effect in the solar system. 95% of the atmosphere is carbon dioxide. The atmospheric pressure on the surface is very huge. Affected by this, you can only run up to 0.6 meters high on Venus, which is about the same as the jump on the surface of the earth.
After leaving Venus, we soon came to the homeland of the earth where mankind has survived for millions of years. It is the third planet in the solar system from the inside out, and it is also the only living planet discovered so far, and it is the place where human civilization was born. I believe many of my friends have tried how high it can jump on the earth. A normal person can only jump about 0.5 meters high.
Let us continue to set off to the moon, which is the only natural satellite of the earth and the only planet that mankind has set foot on. The gravity of the moon is only one-sixth of that of the earth. Such gravity is already very large from the perspective of the satellite. Under normal circumstances, it is difficult for such a huge satellite to become a planetary satellite, so the origin of the moon has always been an important task for the scientific community to continuously explore.
The moon has no atmosphere, and its gravity is much smaller than that of the earth. So you have to be careful about bouncing on the moon, it will reach a height of 2.7 meters when struggling to jump. If you are not careful when you fall, you may get injured. The next destination is Mars.
Mars is a fascinating red planet and the planet most explored by mankind in the past century. Although the surface of Mars is very desolate, a lot of exploration and research have found that Mars may have been a beautiful ecological planet long ago, and life may have also existed. However, the ecology of Mars changed drastically later, and it became like this step by step.
The mass of Mars is much smaller than that of the Earth, so its gravitational force is much weaker than that of the Earth. If it jumps on the surface of Mars, it can reach about 1.2 meters, which is about the same height as it jumps on Mercury. Therefore, if humans immigrate to Mars in the future, our first feeling will be lightness. After adapting to the Martian environment, it will be very beneficial for human survival in the wild on Mars.
Running high naturally also runs far, and can run faster when encountering danger. Therefore, Mars can be regarded as an ideal place for humans to emigrate in the future. Of course, to move to Mars, we must first make various modifications to Mars to make its environment suitable for human survival.
Leaving Mars, we head to a very strange planet, which is Ceres. This is the largest planet in the solar system, located between Jupiter and Mars. The gravity here is naturally smaller. If you rise up and jump, you can reach an astonishing 16 meters. On this planet, we are trapeze.
Moving on, we came to Jupiter, the largest planet in the solar system. Jupiter is a gas giant planet, and it naturally has a solid surface, but we cannot go deep into the Earth’s surface under the Martian atmosphere to perform bounce experiments, and can only test near its orbit.
Since Jupiter has a mass of more than 300 times that of the Earth, its gravitational pull is so strong that even if we bounce on a nearby spacecraft, we can only jump up to 0.20 meters. When we arrive near Jupiter, we will naturally go to Ganymede. It is the largest moon of Jupiter, and it is also a planet where scientists speculate that life may exist. Although the volume of the wood satellite is larger than that of the moon, its mass is not so large, if it jumps hard, it can reach 3 meters.
Saying goodbye to Ganymede, we come to the second largest planet in the solar system-Saturn, which is also a gas giant planet. The biggest feature of Jupiter is that it is surrounded by a beautiful ring of Saturn, which is a system composed of countless ice crystal particles. Don’t look at the size of Saturn, but its mass is comparable to that of the earth. The height of the jump is about the same as the earth.
After leaving Saturn, the next stop we came to Uranus, which is a planet with a strange smell. The structure of Uranus is very similar to Jupiter, and it is also a gaseous planet. At the same time, it is also the lowest temperature among all planets in the solar system. In a cold night, the temperature can reach minus 227 degrees Celsius. The gravity of Uranus is slightly weaker than that of the earth, so the height of Uranus is also slightly larger than that of the earth, which can reach about 0.6 meters.
The next stop is Neptune, a very beautiful dream planet, an ice giant planet. Although its volume is smaller than that of Uranus, its mass is much larger, which is comparable to that of the Earth, so the height of the jump from the surface of Neptune is about 0.4 meters.
At the last stop, we came to Pluto in the Kuiper Belt. It was once one of the nine planets. Later, scientists discovered that it was too small and removed it from the list of planets. Its mass is too small, and the gravity is naturally not large. If it jumps on Pluto, it can reach about 7.6 meters.
Due to the different masses on different planets, the height at which humans can jump is also different. In the future, when human beings move towards the interstellar and begin the path of colonization, we will need to live on many exoplanets. At present, the Earth-like planets that we have observed and found are very similar to the Earth, and most of their masses are larger than that of the Earth. many.
The mass is much greater than that of the earth, so the gravity and gravitation on the surface are naturally much greater than that of the earth. Living on such a planet, we will feel heavy, walking is far less flexible than on the earth, jumping may also become a more difficult thing. Therefore, in the future, when humans choose to migrate to the planet, mass is a very important consideration. In the end, planets that are close to the mass of the earth may be smaller than the mass of the earth.
