• Sun: The sun could be perturbed from its current position, altering its gravitational influence on the entire solar system.
• Inner Planets: Mercury, Venus, Earth, and Mars would face significant risks due to their proximity, potentially being ejected from their orbits or colliding with one another.
• Outer Planets: Jupiter, Saturn, Uranus, and Neptune would experience changes in their orbits. Given their massive sizes, their gravitational perturbations could cascade, affecting smaller bodies and moons.
• Orbital Disruptions: Altered orbits of outer planets could destabilize the Kuiper Belt and Oort Cloud, sending comets and asteroids into the inner solar system.
• Asteroid & Comet Trajectories: The gravitational forces could redirect asteroids and comets, increasing the likelihood of collisions with planets, including Earth.
• Tidal Effects: Close encounters could induce tidal forces, leading to geological and oceanic disruptions on planets and moons.
• Solar System Configuration: The stability of the entire solar system could be compromised, with objects possibly being captured by the passing star or scattered into interstellar space.
• Habitability Changes: Earth’s orbit could shift, leading to drastic climate changes and possibly rendering it uninhabitable.

These interactions would unfold over extended periods, ranging from thousands to millions of years, depending on the specifics of the star’s trajectory.
