The orbits of planets around the sun are slightly? or oval shaped?

the further away you are from the sun, the more oval shaped you get. the closer you are, the more circular the orbit gets.

The planets, starting farthest from the Sun are Pluto, Neptune, Uranus, Saturn, Jupiter, Mars, Earth, Venus, and Mercury ... It also is the second brightest object in the Solar System, after the Sun. The moon appears to wobble a bit; this happens because of its elliptical or oval-shaped orbit.
