Summary:
-
Our solar system may have been sculpted by a passing old star, creating unique patterns in its outer fringes.
-
The theory of a stellar flyby explains the formation of the Kuiper Belt and potentially the Oort Cloud.
-
This encounter could also explain the orbital tilts of extremities and the need for Planet Nine.
Our solar system might have undergone a sensational experience even before it turned into a blue planet with life. According to simulated works and astronomical findings made recently, a passing old star- a visitor to the universe- might have sculpted the outer fringes of our solar system. This is one of the most interesting theories whose main aspects are these at minimum.
The Solar System was formed in a Star Cluster
Scientists feel that the Sun did not form in isolation but rather in a high concentration stellar nursery. Close interactions between young stars in such crowded conditions were favored.

A Stellar Flyby Is Physically Viable
Computer simulations indicate that in an incident where another star had been positioned too near them, that through the regions of the latest solar system, its gravitational force was able to pull the outer parts of this system.
The Kuiper Belt Holds Clues

There are numerous rocky objects in this remote area with asynchronously elongated and tilted orbits. The only way of explaining these patterns is through consideration of the gravity of the known planets.
It is possible that the Encounter created the Oort Cloud
this huge spherical, shell of frozen bodies which surrounds the solar system may well have been formed, at least in part, as a result of debris thrown out into space during a stellar fly by.
It Has the Potential to Explain Orbital Tilts of Extremities
Dixth some other distant objects are spinning around on angular sides of the main planetary plane. This strange alignment could be explained by a gravitational attraction of a passing star.
Another Way of Planet Nine
Though some astronomers may be tempted to say there is some unknown giant planet to cause strange orbital precession, other astronomers may say that some earlier stellar contact might generate such effects without the need of an unknown planet.
Timing Was Critical
Should the collision have been made, it would have taken place during the first 100 million years since the solar system began to form – at the time when planetary orbits were yet to be established and more easily disturbed.
Numerous Solar Systems Could have Common Past
In the case that stellar flybys were frequent in young star clusters, then the other systems of planets throughout the galaxy would have the scars of ancient contact as well.
It Illuminates an Even More Anarchic Early Solar System
Instead of developing in quiet solitude, our solar system might have developed in an active, crowded suburb, not only due to forces within its own system, but also due to the passing cosmic neighbors.
