The planets found it boring to just orbit the equatorial plane and therefore they decided to orbit other planes
![]() Well, I assume the solar system in the beginning was a chaotic system, with the gravitations of the protoplanets influencing each other and also extrasolar objects (other stars for example) exerting gravitational influence (which, even if small, might still be significant in the range of milions/billions of years). So that only after millions/billions of years the orbits stabilized into the orbits we know today. This would also explain why only mercury as planet closest to sun (and therefore being the planet who is the most influenced by suns gravity) has the orbit with the least inclination. |

Here's a good diagram of the tides (the moon is off to the right): ![]() If the Earth had no moon, the surface of the ocean would be determined solely by the Earth's gravity (it's an equipotential surface) and would therefore be basically spherical. However, the ocean and the Earth are both orbiting the moon*. On the side of the ocean closest to the Moon, the gravitational field is slightly stronger than at the center of the Earth (or the sides of the ocean facing perpedicular to the moon). Thus, the water on that side is pulled closer to the Moon than the rest of the Earth or the ocean. By the same math, the water on the far side of the Earth is less attracted to the Moon than the rest of the ocean, so it ends up going even farther away from the Moon. Result: the thing in the picture. I don't know WTF you're getting magnetic fields from. * well technically they are orbiting the common center of mass. Not important. |
