is it solar wind ? or the agnetic field of the sun or the sun s gravity or no force is needed ?

Gravitational force is actually between two objects, not just one, so technically is would be gravitational foreces between other objects, ie the other planets and the sun. The sun is not the only object that gravitational force exists between, it just has the greatest force.

The gravitational pull of the sun, but the orbits are somewhat elliptical due to other weaker gravitational forces that intervene at different stages of the orbit. And there is a sort of "momentum" effect that gets built into certain orbits over time that may increase the elliptical shape.
Someone referred to centrifugal force, but in actuality they are referring to the aforementioned "momentum," or the speed of the object that is then pulled into the orbital shape by the gravitational force between it and another object.. An object traveling in a circle behaves AS IF it is experiencing an outward force. This force is referred to as the centrifugal force, but it is important to note that the centrifugal force does not actually exist.

The orbits are determined by balancing the planets centrifugal force,that pulls them away from the Sun and the force of gravity that pulls them toward the Sun.

Any merchandise shifting in a straight away line, if subjected to a stress appearing perpendicular to its route of action and pointed continuously in the route of a troublesome and quickly element, then the action of the article will be round. yet for the gravitational charm of the planets with techniques from the solar,the route of the planets will be in a straight away line. because the solar pulls the planets in the route of it, the planets bypass in a round route.

it is theorized that there are "dents" in space caused by the planets. these "dents" are tracks for the planets to orbit in. they are sort of like the coin slots that when you put the coin on the top and let go, it spins down the hole into the area below it, except the planets are not falling deeper inot their respective "dents."
