Why Are All the Planets on the Same Orbital Plane?
Is it a coincidence? Or is something else at play here?
When we imagine the solar system, we tend to have this concept of a flat disk with lots of rings indicating the orbital motion of the planets.
Given that we’ve learned this since we were little, we kind of take it for granted that all the planets are on the same orbital plane.
Not only that, but they all orbit the Sun in the same direction.
But have you considered, why?
Is it a massive coincidence?
Or did something happen to make it this way, and if there was a process, do we have evidence of it elsewhere?
