All planets actually follow an elliptical orbit.
venus because the orbit is like a kind of oval and the other planets orbit looks straight
Planets orbit stars.
Moons orbit around its planet while the planets orbit the Sun, therefore moons circle the Sun.
To orbit in a precise circle, it would require a very specific speed. Any variation, and the orbit turns into an ellipse. If ever Earth's orbit WAS a circle, the tug from other planets in the Solar System, as well as any other object that happened to pass nearby, would change it to an ellipse.
None of the planets orbit the sun perfectly in a circle, there is a degree of deviation from this perfect circle called eccentricity. The higher the eccentricity (more more the eccentric the orbit is) the further away from this perfect circle the orbit is. The planet that deviates most from a perfect circle, having the highest eccentricity, is Neptune. Neptune also has the highest axial tilt, tilted over onto its side as it orbits the sun.
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.

The gravitational pull.
If you mean the trajectory of the planets around their parent stars, it is called the orbit, and it is not a circle but an ellipse
Kelper determined that the orbit of Mars orbit is not a circle but an ellipse.
All planets circle the CEntral Star. So in a way outer planets almost circle inner planets but the Star is at one focus of the planets' orbits so it is more proper to say that planets orbit stars.
The name is orbit, planetary orbit
Kepler
The planets orbit the sun in an ellipse, like a squashed circle. The amount by which the ellipse is deformed by, from being a circle, is referred to as the eccentricity. An object with a highly eccentric orbit, such as a comet, will have a very elongated and stretched out orbit, its distance from the sun throughout its orbit will vary by a lot.
