How does the earth revolve around the sun?
First of all, if you were looking down on the sun from its north pole you’d see the Earth going around the sun in a clockwise direction. The strong gravity of the sun is constantly trying to pull it down into it, but at the same time Earth’s speed through space is trying to move it out away from the sun. Both of these forces exactly cancel each other so that the end result is Earth moving in a big circle around the sun.
The planets, except for Pluto, revolve around the sun in nearly the same plane. That means, if all the other eight planets were revolving around the sun on a table top, that’s where you would find them, on the plane of the tabletop. As to how, I think you mean in which direction. As seen from the north pole of the sun the planetary system, all the planets, would revolve in a counter clock wise fashion. If you mean by “How”, then, its because of gravitational pull as explained by Einstein. All the planets fall into the sun at the same distance as their orbital speed propels them away form the sun. the result, a reliable repeatable orbit that is elliptical. ….
When you ask how do you mean the actual mechanism? It revolves around the sun as a result of the gravity of the sun keeping it in orbit – the planets move around the sun now because the disk of gas and dust they were formed out of was rotating (its the rotation that started the formation of our system). If you mean what does it look like, its an ellipse – meaning that its not a perfect circle but a little squashed, with the sun at one focus of the ellipse. So in January we are closer to the sun than we are in July.
