Wow, you like to throw out scientific terms you don't know the meaning to. And regardless of whether or not you "like to think" planetary orbits are circular, it is obviously not true, considering Pluto's orbit is so eccentric there are times when it can be closer to the sun than Neptune.

For the record, the motions of solar objects are best described as conic sections. When Newton invented calculus one of the first things he proved was this basic fact.

While it can be helpful to "view" confusing scientific notions through a mental filter of some kind to aid in your clarity and understanding, don't let that filter obviate facts you know to exist.
