Scientists have proposed a new theory that could change our understanding of how the solar system formed. According to this hypothesis, billions of years ago, an interstellar object could have collided with our system, causing significant changes in the orbits of the planets. The new study has not yet undergone peer review and is published on the preprint server arxiv.org . The solar system is thought to have formed about 4.6 billion years ago from a cloud of gas and dust around the young sun. The planets gradually settled into stable orbits, but some anomalies remain unexplained. For example, the orbits of Jupiter and Neptune have small deviations that are difficult to explain with traditional models of planetary migration. A new study suggests that an interstellar object 50 times the mass of Jupiter may have passed through the solar system. The event could have occurred as close as 20 astronomical units from the sun and significantly affected the orbits of the planets. Computer models show that the probability of such an event is about 1 in 100. Despite the low probability, this scenario deserves attention, as it could explain many mysteries of the solar system. The researchers suggest that the object that caused these changes could have been a rogue gas giant or a fragment of interstellar structure. If this theory is confirmed, it will force us to take a different look at the evolution of stellar systems and the influence of cosmic objects on the formation of conditions for life. Further research will help to refine this theory and find evidence for its validity.
