How do forces affect the planets of your solar system?
With gravity and inertia. If you dont know what those look them up in a scientific dictionary.
It is not likely that any black hole gets near the Solar System in the short term - "short term" meaning, the next few million years at the very least. In the unlikely event that a black hole does get into the Solar System, I would guess that the greatest risk is that it disrupts the orbits of planets - perhaps even flinging planets out of the Solar System.
The first eight planets in the solar system, counting from the sun are the following: Mercury, Venus, Earth, Mars. These are called the "Inner planets". Jupiter, Saturn, Uranus, Neptunus. These are called the "Outer planets". The asteroid belt between Mars and Jupiter forms the boundary between the inner solar system and the outer solar system. These 8 planets are the only planets known in our solar system.
