hang on a second.... our solar system??

don’t you think we would have seen them by now??

and didn’t they say that our solar system really ends at the Oort Cloud??

If they are far enough away they may only have moved through a small portion of their orbit since people had access to real astronomical telescopes.

The Oort cloud is still theorhetical but likely and possibly believed to extend nearly half way to Alpha Centauri.

The definitions of what is and isn't in our solar system is kind of open to interpretation. In my interpretation, anything under the gravitational influence of our sun is within the solar system.
