Why our solar system follows a cosmic highway instead of chaos
In short: The planets don't wander randomly; they follow a remarkably flat, orderly path across the sky. This video explores the violent history that organized our neighborhood into a structured disk and why this alignment might be our best defense against space debris.
Our solar system's co-planar motion originated from a collapsing cloud of gas and dust. As this cloud spun, it settled into a disk structure due to the conservation of angular momentum—a balance between inward gravitational collapse and outward centrifugal force.
This process explains why every planetary system discovered so far follows a similar flat pattern. The Sun's spin axis aligns with the rest of the planets because they formed from this same rotating material. This organization also serves a protective role, as it helps eliminate asteroids that do not follow these established orbital rules.
