Nothing is perfect.
All planets actually follow an elliptical orbit.
The planets do not circle the sun in any specific shape. Their orbits around the sun are more elliptical than circular, and each planet has its own unique elliptical orbit.
If you mean in our Solar System: All of them. All are elliptical, but all are very close to a circle.
Mars's orbit is more elliptical than all the eight major planets except Mercury. This enabled Kepler to discover that the orbit was elliptical and not as previously thought a circle with the Sun offset from the centre (represented by a circle and an epicycle with the centre of the epicycle travelling round the circle, and the planet positioned on the epicycle).
in a oval shape not really a circle ANSWER:OVAL
The orbits of planets are not quite circular. They are slightly elliptical. An ellipse is like a circle which has been squished.
Planets circle in an elliptical orbit around the Sun.
No, because all planets known have elliptical orbits.
About the same shape as an egg, or oblong. Not a perfect circle.
it looks like a circle seen slightly on edge
Oval or elliptical shaped. (Not a perfect circle)

They are all approximately circle and in the same plane, but when you look further, they are actually elliptical and off centre from the sun. They also tend to have slightly inclined planes. These eccentricities mean that planets are sometimes closer to the sun than at other times.

There is a common misconception about what causes the seasons. Many will say that it is due to the elliptical orbit of the planets, and we are further away from the sun in winter, and closer in the summer. THIS IS NOT THE CASE!!! Consider the fact that when it is summer in the northern hemisphere(The Upper Half of the Earth above the Earth), it is winter in the southern hemisphere. The actual reason that we have seasons is that the Earth is tilted on its axis. So instead of spinning upright in relation to the sun (like this |), it spins on a tilt (like this \). Thus, one half of the planet is slightly closer to the sun, and it is slightly warmer. Earth's orbit is elliptical, but it is very close to a perfect circle. However, most drawings of the solar system exaggerate the elliptical orbits, thus leading to the common misconception.
It is an ellipse. The orbits of all the planets are ellipses, though the orbit of Venus, while elliptical, is very close to being a circle.
