In one sentence I need to describe the shapes of the orbits of the planets. The shape must be accounted for in a model of the solar system, and of the solar system formation. My answer would be that the shapes of the orbits are round. Yet this seems to obvious! Need help.. is my answer right, wrong?

Here in Texas, we observe the orbits to be elliptical with one Foci very near the Sun's geometrical center.

They are elliptical, almost circular.
