Jupiter declared the oldest planet in the Solar system


The core of Jupiter was formed 4.6 billion years ago, just million years after the Solar system much earlier than any other planet. This was stated by experts of Livermore national laboratory and the Westphalia University named for Wilhelm.

Previously it was assumed that Jupiter was formed quite early, however, to call it the exact age of the experts was not ready. In the new study, the researchers analyzed the composition of two meteorites that appeared at the dawn of the Solar system, 2-3 million years after its occurrence. The composition of meteorites differ so much that they should appear was in different “reservoirs”. Experts suggest that the transport of solids from one part of the Solar system to another could interfere with the core of Jupiter, if it had already formed and the mass exceeds the earth’s, at least 20 times. To date, Jupiter is 318 times bigger than Earth.

According to experts, the study indirectly allows to answer the question, why in the Solar system there is no one cosmic body, the size of a superior planet, like the earth, but inferior to the gas giants, while in the whole Universe of such “super-earths” are quite common. According to experts, this may also be due to “separation” of the Solar system, provoked by Jupiter.

The study was published in the scientific journal Proceedings of the National Academy of Sciences.

Jupiter is the largest planet in the Solar system. Its name it received in honor of the Supreme deity of the Roman Pantheon.5 Aug 2011 it was running a research station, and nearly five years later, she came in his orbit.

In November last year, scientists found that the “correct” location of Jupiter and Mars, could be one of the prerequisites for on Earth life began. If Mars did not exist, and Jupiter were closer to the planet, its orbit would have been more extended, and this could lead to the fact that the Land is not preserved ocean of liquid water. Some researchers believe that Saturn and Jupiter in the far defended the Earth from large objects, collision with which would affect her chances of becoming inhabited
