Yes, our Sun is part of a binary star system. It is in a binary system with a smaller star called Alpha Centauri, which is about 4.37 light years away from Earth.
A binary star system forms from a collapsing cloud of gas and dust. As the cloud collapses, it breaks up into smaller clumps which eventually become individual stars. If the clumps are close enough, they can orbit each other and form a binary star system.
No, we cannot see the other star in our Sun's binary system with the naked eye. Alpha Centauri is too far away and not bright enough to be visible to the naked eye. But, with the help of powerful telescopes, we can observe and study it.
The presence of a binary star system does not have a significant impact on our solar system. The gravitational influence of Alpha Centauri on our Sun is minimal, and the distance between the two stars is too great to have any significant effects on our planets.
It is possible for our Sun to become a part of a different binary system in the future. As stars age and evolve, they can exchange partners and form new binary systems. However, this process takes a very long time and it is unlikely to happen within the lifetime of our Sun.
