Jupiter is a planet without a nucleus. How was its nucleus lost? Scientists solve your doubts.
Astronomers believe that to some extent, Jupiter's core seems to have disappeared, which can be explained by Jupiter's collision with a planet. The mass of this planet that collided with Jupiter may be 10 times that of the earth.

In the early history of the solar system, the probability of collision between planets is very high, so it is not surprising that there are planets colliding with Jupiter. Thinking of our earth, scientists speculate that the earth's own moon was caused by a huge impact. Similar events may be the cause of some unexpected features of Jupiter's core, which is low in density but high in heavy elements.

NASA's Jupiter Orbit Juno mission has detected Jupiter's gravitational field in detail, and scientists can understand the internal situation of this gas giant planet by studying the gravitational field. Judging from the distribution of Jupiter's gravitational field, the core of the planet may actually be more dispersed, but there are many heavy elements, not a very dense central core, and the surrounding environment is low in density. .

According to the paper published in the journal Nature, researchers in the United States, China, Japan and Switzerland want to know how such a planet became like this, which runs counter to most planetary formation models. But there is a hypothesis that can explain this result: Jupiter's early huge impact.

The solar system is formed by a disk of dust around the sun, which condenses into planets and other celestial bodies. During this time, planets like Jupiter will grow rapidly and suddenly exert great gravity on the surrounding planets (on the time scale of the universe). Perhaps, as a result, a smaller protoplanet nearby may collide with Jupiter. In fact, the researchers' Jupiter formation model and collision predict the conditions for the formation of planets, which seems like researchers know Jupiter.

According to reports, this kind of impact will not be a knock on the celestial body slowly swallowed by Jupiter, and it will not produce a shock wave enough to destroy Jupiter's core. Scientists speculate that this planet must hit Jupiter head-on and have a very large mass in order to generate enough impact to destroy Jupiter's core.

Therefore, although the huge collision is not certain, it is very helpful for continuing to explore Jupiter, especially for the construction of the scene where Jupiter formed.
