First of all, sorry if my question topic was vague and did not even tell you what my question was remotely about. I just could not think of the right words for it.
I was thinking one day and something came up in my mind about the solar system. When you look at images of galaxies you see that they are flat because gravity and their rotation flattens them out. However, I was wandering why planets in solar systems have to be set out flat going around their star like galaxies do. Could planets in theory rotate around their star in completely in set orbits but at different vertexes? My knowledge of cosmology is not that detailed, I only do some amateur stuff myself, but the suns gravity on the Earth and other nearby planets is not very strong. Could planets rotate on different vertexes, but also going in the same direction as the star or the sun in our case? It could just be simple like galaxies in the universe, but I just randomly thought this up and was wandering if it had any substance to it.
