Neptune's orbit is an ellipse. The aphelion (farthest from Sun) is 4.54567 x 10^9 km, and the perihelion (closest to Sun) is about 4.44445 x 10^9 km. The eccentricity is therefore about 0.009.

The orbits of all planet are ellipses. The eccentricity (the ratio of the widest part to the narrowest part) varies. Most plannet's orbits have such a low eccentricity that, when viewed from above, they appear circular. Pluto is the only planet with a noticable eccentricty.
(Pluto will always be a planet in my heart ;>)

Its a elipse and it is found using the formula to find the eccentricity of the orbit, where 1 is a perfect straight line, and 0 is a perfect circle

neptunes orbit is circular and retrograde and has an inclination of 23* with respect to the plane of Neptune's equator.
