Is space structured like a flat plane where all planets align along a single y-axis, or is it akin to an expansive ocean where planets occupy positions across multiple axes?

Is space structured like a flat plane where all planets align along a single y-axis, or is it akin to an expansive ocean where planets occupy positions across multiple axes?

Answer 1

Planets are generally in a plane. Best way to think about it is to imagine long time ago a cloud of debris orbiting the sun across many different planes. Eventually (billions of years) they collide enough that the stuff that’s left is generally in a plane and can’t collide anymore.
