Another Solar System coming to Collide with ours

The Andromeda Galaxy is on a collision course with the Milky Way Galaxy. You might go hide under your bed in 4 billion years.-Current calculations have the comet doing a clean (if still close) miss of Mars 14 months from now.Itll still be a spectacular sight since itll be about 37,000 kilometers from Mars surface. Hopefully,......
As far as colliding with another stellar system, it really depends on how you define "collide". Stellar systems (like ours) are overwhelmingly empty space, so even if two systems were on a collision course, the odds are against anything significant running into anything else significant.
All stars (and the planets they have) orbit the center of the galaxy, and while most of them have nearly circular orbits, they're not perfect circles, so things move closer together and further away over time. A long time. The next time a star gets within just over 1 light year from the sun is when Gliese 710 passes 1.1 light years from us--in about 1.3 million years.

Either you didn't pay attention or where ever you got this bullshit is not a place to get credible info from. You want scared? The Andromeda Galaxy is on a collision course with the Milky Way Galaxy. You might go hide under your bed in 4 billion years.

Current calculations have the comet doing a clean (if still close) miss of Mars 14 months from now. It'll still be a spectacular sight since it'll be about 37,000 kilometers from Mars' surface. Hopefully, the current crop of orbiters and rovers will able to snap some pix of the passage.

Can we see another star cloe up? No, ergo no solar system close.
At the speeds involved an intersection then wouldhave another star on our doorstep.
If you realy want to worry - the planet that hit the Earth to form the Moon is relativelly close.

No, there is only one Solar System because there is only one star called Sol, or more commonly called the Sun.

Possible but not likely cause the Sun would capture the object in its gravitational pull . Therefore in its orbit.
