Juno, who entered the Jupiter orbit in 2016, renews the awareness of the planets of the solar system Big Mac. Recently, scientists analyzed the image of a volcanic eruption on the Io surface when analyzing the data that Jupiter sent to the 17th.
From the time of the universe, people successfully released Jupiter-related detectors nine times in total. Despite receiving some of the giant planet and some of the satellites and rings systems surrounding it, Jupiter still has many unsolved mysteries. For example, in 2018, US scientists claimed that they found 12 satellites from Jupiter, bringing the total number of Jupiter satellites to 79, which overshadowed other planets in the solar system. Where does the big attraction of Jupiter come to the satellite?
Big head: Big brother in the planet of the solar system
Before answering this question, you must first find out where Jupiter comes from.
Planets originate from the material disk. "The small particles of dust on the material disc collect together to form large and small masses, called" Xingzi ", and the stars collide with each other to form a larger mass." Kong Dali, a researcher at the Shanghai Academy of Astronomy, China Science Academy, told a science and technology journalist Daily said the masses The higher the gravity, the stronger the surrounding gas, and the more gas around you can "grow" more quickly. At this point, other small stars can only "dry their eyes" even if they want to increase again, because there is no gas surplus around them.
If you use the "heads" to talk about heroes, Jupiter will undoubtedly have a noble "birth" of the group. As the largest planet in the solar system, its volume is about 1321 times the volume of the Earth, its mass is 1.888 × 1027 kilograms, about 318 times the mass of the Earth, and 2.5 times the mass of the mass of other planets in the entire solar system . Its essential part can be 10 times the weight of the Earth, and it is a well-deserved "big brother" on the planet of the solar system.
Why is Jupiter's size and quality "remarkable"?
Former NASA astrophysicist Jenny Kavinos in the National Aeronautics and Space Administration (NASA)<星球大战>"Science in the book" writes that the shorter the size of the orbit than the star, the less material is made to make the planet. Therefore, in theory, the closer the planet is, the smaller the planet's circumference, the farther away from the star. The bigger the planet.
Outside the sun, the temperatures are lower, and more matter condenses, such as water, methane and ammonia, which form the nucleus of extraterrestrial planets. The larger the planet, the stronger the gravity. This means it can attract more light gases and gather around the planet to become a huge atmosphere. This process has caused a far distant planet, and Jupiter is one of the most outstanding representatives.
Kong Do you believe that Jupiter's quality is consistent with chaos in the universe, and there is no definitive explanatory theory. "It's like sprinkling flour in the water, the flour does not melt immediately, it forms large and small particles, and we have no way to decide who gets bigger and which decreases." Jupiter's mass is better than other planets in the solar system. so very strong random. "
