Don_DickleHow come planets move around in a circle for left to right or whatever? Why not a up and down circle like a target logo? I can explain further. thanks ahead of time.
In space there is no up and down.
Ok the planets move in a circle laying down. How come not a circle standing upright?
667It all depends on your reference point. Typically when orbits are depicted for human understanding, they’re given a top-down view. Think like Open Street Maps. It could be depicted on its side, like watching race cars around a race track, but it can result in more visual distortions than a simple top-down view.
Alternatively, if you’re referring to orbits with high inclinations relative to the orbital plane, that also happens. Pluto, for example, has an inclination of ~17°, which is one of the reasons there are theories it was not part of the solar system when the solar system formed.
