Why are models of our solar system always shown with the planets rotating the sun in a 2D plane?
For the most part they do rotate in an almost 2D plane. I think Uranus's orbit is slightly skewed from the rest of the planets, but for the most part it's the most stable orientation. It's kind of like how Saturn's rings are all settled in a single plane as they orbit around the planet, due to th…
The Short Answer
For the most part they do rotate in an almost 2D plane. I think Uranus's orbit is slightly skewed from the rest of the planets, but for the most part it's the most stable orientation. It's kind of like how Saturn's rings are all settled in a single plane as they orbit around the planet, due to the gravity of the debris also having an effect on each other, pulling everything as close together as possible while still maintaining a stable orbit. Basically a similar thing happened around the sun in what is called an accretion disk. Eventually, clumps of the disk gathered together in more dense chunks, and the bigger the chunks, the heavier they got, the stronger their local gravity wells become, and the more debris they attracted, until these clumps all condensed into what are basically the planets, their moons, and the asteroid belt; all orbiting in roughly the same plane as they did before.
