Fun little fact: you'll notice that the orbit has a wobble where the solar system dips down and up past the galactic disc. Each time we're more likely to be exposed to the gravitational influences of other bodies passing by, which tugs on the Oort cloud and potentially makes asteroids bounces back inwards to us and increases the risk of Earth getting hit by an asteroid.
