How many times the size of Jupiter is that of the earth? Why can't humans live on Jupiter?

Jupiter is the largest planet in the solar system. Jupiter's mass is about 3 18 times that of the earth, its diameter is about 1 1 times that of the earth, and its volume is about 1300 times that of the earth. There is a super storm on Jupiter that has been raging for more than 300 years-the Great Red Spot. You can put down an earth! If Jupiter is as big as a basketball, the earth is just a glass marble with a diameter of 2 cm. The diameter of the earth will increase by 1 1 times, and the area of the earth will increase by 12 1 times. Suddenly I feel that the whole world is at peace. Because the territorial area of each country has increased by more than 120 times, there is no territorial dispute. Mongolia is the country with the lowest population density in the world, with a small population, with only 1.5 people per 100 square kilometer. Visiting a neighbor's house may take hundreds of kilometers.

The earth suddenly becomes the size of Jupiter, and the biggest impact on people is that it is inconvenient to go out. It turns out that it only takes 42 hours for an ordinary civil aviation plane to fly around the equator. Now the earth has become as big as Jupiter, and it takes 19 days to circle the equator at the same speed. This also requires the plane to fly all the time. Scientists should study and prove that rocky planets like the earth can't be too big. If its mass is more than three times that of the earth, it is difficult to form a rocky planet, just like Jupiter.

Don't fantasize that the earth will become a planet like Jupiter. If so, there would be no human beings, or even life! It also starts from rocky planets and collects heavy element dust. However, in its position, far enough from the sun, water can exist in a solid state. In this way, it has enough matter to increase to four times the mass of the earth in just three million years. This mass makes it have enough hydrogen and helium, and then it becomes the most abundant gravity on the planet.

The solar system can't be a terrestrial planet as big as Jupiter, because the sum of all the stars in the solar system is not as big as Jupiter. However, terrestrial planets may exist in other star systems. The formation of big planets is the merger of many planets in the universe. From the time scale of hundreds of millions of years, planets will migrate in different orbits. At the same time, it may collide and merge. If Jupiter merges with other planets, it can get more important elements.
