If there was a planet between Mars and Jupiter, it could push Earth out of the solar system and thus wipe out life on our planet. This is the conclusion reached by UCR Roverside astrophysicist Stephen Kane, who explained that his result is part of a study that wanted to address several gaps in planetary science.

According to him, the first goal was to understand why there is such a large gap between the Earth-like planets and the gas giants in our solar system. The largest of the terrestrial planets is Earth, while the smallest of the gas giant planets is Neptune, which is four times the diameter of Earth and 17 times larger.

"In other solar systems there are many planets with masses between these two limits, planets that we call super-Earths," explains Kane, who adds that there are no intermediate-sized planets.

The other element of the study was to understand why there are no planets between Mars and Jupiter. In fact, "planetary scientists argue that there should be at least one terrestrial planet in that space."

To solve these two problems, Kane has performed dynamic computer simulations and among other things he wanted to insert a planet between Mars and Jupiter, and he did this by predicting a number of different masses to verify what it would produce in the orbits of nearest planets.

The results published in the "Planetary Science Journal" say that a planet in that space of the solar system would have been a big problem.

“Its existence would have given Jupiter a small gravitational boost, but it would have been enough to destabilize all the other planets. So, if a planet in that position would have given a "touch" to the solar system, giving it greater uniformity, in reality it would have profoundly changed it. So it's good that it doesn't exist," Kane explained.

Jupiter is much larger than all the other planets combined. Its mass is 318 times that of Earth, so its gravitational influence is great. If a passing star or other object passes close to the solar system and disturbs Jupiter's orbit even slightly, all the other planets will be deeply affected.

Depending on the gravitational change it may undergo, Jupiter may even push Mercury, Venus and Earth out of the solar system, and Uranus and Neptune on the other side.

As for Earth, even if it were not pushed by the solar system, its orbit would be altered so much that the conditions to support life could fail.

The result of this study says how giant planets like Jupiter present in many solar systems discovered in recent years can affect the existence or not of life on smaller rocky planets.

"Our solar system is much more subtle and organized than previously thought. It works like a gear clock. Put one more gear and everything falls apart," concludes Kane.
