Will there be any more planets come into our solar system and make it their "home"?
Short answer: Yes, but it is very unlikely.
The probability that a random object drifts into the Sun's sphere of influence (SOI) is low (excluding tiny stuff like space dust and small rocks). But the chance that a full-blown rogue planet enters our Solar System is many orders of magnitude lower. Let's set up a Drake equation:
Let $R_n$ be the number of rogue planets in the galaxy, $R_{ns}$ the fraction of rogue planets that may enter the solar system, $R_e$ be the probability that one enters the Sun's SOI, $R_i$ be the probability that the planet will survive an encounter with a Solar System planet, $R_s$ be the percentage of all possible orbits for the rogue planet after the interaction that are long-term stable, and $R_o$ be the probability that the rogue planet gets captured into an orbit. Therefore, $$R_o=R_nR_cR_iR_s$$
