Why is the orbit of the Earth around the Sun very intricate? The movement of the earth around the sun is very Goldilocky. Did it happen over the years as the orbit of earth averaged out into how it is now? Is there any chance of it (orbit) changing by itself in the future without the interference of external factors? 
Also how is it so stable? And what drives it? Is the sun pulling it once it is far away, gains speed, goes around the sun and as it goes away it again loses speed due to the sun's gravity and the whole cycle repeats?
 A: Orbits around the sun are ellipses. Any small perturbation will produce another elliptic orbit. So in this sense they are stable: they do not change their shape greatly unless one adds enough energy to turn the orbit into a parabola or hyperbola, which are unbound. So that Earth has retained its orbit over 4.5 billion years is not strange. Even big meteor impacts will just nudge the orbit but not change its nature. 
The reason for this is how Newtonian gravity works: because the force scales as $1/r^2$ bound orbits are closed (Bertrand's theorem).
A: First, the sun has a large amount of protons on the plasma, so it has a positive charge.Next, the ionosphere of the earth is positive and the surface is negative.The charge of the sun and the earth has been confirmed in mainstream science.
As the Earth approaches the perihelion, the effect of the solar wind increases the positive ionosphere.The Earth moves away from the sun, as the positive force of the sun increases.
As the solar wind decreases as the earth goes to aphelion point, the positive charge of the earth decreases and the repulsive force also decreases, so the earth approaches the sun.
As the earth approaches the sun, the positive charge increases and moves away, and as it goes away, the positive charge decreases and approaches.There is also the influence of the solar wind's standing waves that the solar oscillation makes, but if I write this it will be criticized for not being mainstream science, so let's stop it.
