No planet's orbit is perfectly circular. They are all elipses.

It must be near circular orbit obeying certain laws of celestial body rotation.
All planets in our solar system, including the the Earth have an elliptical orbit around our Sun. In Earth's case, the orbit is nearly circular.
Yes, comets orbit the sun, but usually in an eliptical (oval) or eccentric orbit rather than a more-or-less circular one like the planets.
An elliptical orbit
circular
The orbit of the planets in our Solar system are not perfectly circular, but eliptical. Each planet also has its own unique orbit, no two planets share an identical orbit. Because of the elliptical (oval) orbit of planets some get close to each other or cross the path of another planet's orbit.
that all the planets orbit around the sun, and that orbit's are not circular.
As with all the planets, the orbit of Neptune is a nearly circular ellipse.
No. Planets orbit the Sun (or some other star) in ellipses.
Circular orbits are unstable; any outside influence (i.e. other planets) will distort them. Elliptical orbits are self adjusting.

They all do. Some planets are closer to a circular orbit than others (have a lower eccentricity), but none are exactly circular.
The orbits of planets are not quite circular. They are slightly elliptical. An ellipse is like a circle which has been squished.
Generally speaking, yes. It should be noted however that the outer planets have a more elliptic orbit (egg shaped).
Venus has the least eccentric (most nearly circular) orbit of the eight in our solar system.
