It could, but it also could have the opposite effect. This was one of my undergrad projects: I simulated Solar system (the Sun + all planets) and studied how comets coming from the outside affect the system's behavior. Small or very fast comets didn't affect anything much, but large comets going at the speed comparable to that of planets rotating around the Sun would either tear Pluto off the system, making it drift away from it, or pull it closer to the Sun - depending on at what time the comet passed near it.
slightly outdated on the regard of gravitational waves.
But still good explained.

Size wise? not more than ~ Jupiter. What you care about though is its mass, and mass wise it can't be larger than ~40-80 Jupiter mass (above this its not a "planet" anymore). If this kind of object gets trapped in Solar system than yes it will probably "fuck it up" in few cycles kicking few planets (depends on which orbit it gets trapped, more dmg in closer orbits). The sun itself will barely notice it as a planet highest mass is still only 8% of the sun mass (yes the sun is NOT a "typical" star - it is actually quite massive).
There are different types of liberal ideologies and different types of ideologies that the right wing encompasses. And within these subsets of ideologies there is some room for overlap (socially liberal and economically conservative, for example). So what you've said is technically true. However, very few people would actually identify as liberal and right wing -- they'd be more likely to say that neither group represents them. So while "liberal" and "right wing" may not be mutually exclusive, as far as self-identification is concerned, they pretty much are.
