Our solar system is unlike anything else discovered so far in the cosmos, and a villainous baby Jupiter could be the reason why it's so funny … and even at home in life. The solar system consists of four inner planets: Mercury, Venus, Earth and Mars. They are known as terrestrial planets because they consist mainly of heavy metals such as iron and nickel. Compared to other planetary bodies, they are quite small and their atmospheres are thin. Meanwhile, the gas giants in our outer solar system – Jupiter, Saturn, Uranus and Neptune – are much larger. And unlike other observed gas giants in the cosmos, they are really far away from their parent star ̵
For years our solar system was the only model we needed to learn from, but thanks to NASA planet hunters like the Kepler Space Telescope, everything changed. Astronomers have discovered more than three thousand exoplanets orbiting other stars, and part of them are in multiplanar systems. So far, scientists have found that the "typical" multiplanet system consists of some super-Earths – extrasolar planets with masses larger than our own, but less so than the gas giants. They tend to be similar in size, with evenly spaced orbits and are closer to their stars than Mercury is to the sun.
We can not really say for certain why our solar system is so different from others, but some scientists point to our largest planet as a possible explanation. One theory leads us back to the birth of the solar system billions of years ago. She claims that the sun was once surrounded by first-generation inner planets on their way to "super-earths." As the planets formed, it was believed that young Jupiter began to wander inward in a scenario known as the "Grand Tack." It claims that as Jupiter moved toward the sun, its gravitational perturbations caused the orbits of the planets that led to catastrophic collisions. Some of the premature planetary pieces were spiraled into the sun while others floated in space. Jupiter was reportedly withdrawn to its present location as Saturn began to form, and the remnants of its chaos into a second generation of planets or the inner solar system as we know it today. If true, the grand-tack scenario helps explain why the terrestrial planets are much smaller than typical super-earths.
Some scientists even believe that Jupiter's disorderly wandering might explain how liquid got to Earth. As the gas giant retreated into space, its attraction for asteroids that formed beyond the snowline, the distance from a star where icy links can condense. Jupiter possibly threw icy space inward toward the asteroid belt and the region where the earth formed. It is believed that these icy asteroids could have supplied enough ice to explain the oceans of the Earth – essentially to provide us with the building blocks for life.
The Grand Tack claims that if the juvenile Jupiter had not swung like a wrecking ball through our early solar system, the earth would never have been created and we would not be alive today. It is clear that we still have much to learn about our alleged cosmic creator, because after all, these scenarios are still theories. But they help to answer many of the growing questions about the curiosity of our solar system. And if, as some scholars believe, they follow the truth, we owe a lot to Jupiter.
