All planets actually follow an elliptical orbit.
It is called an ellipse.
The orbit of Earth around the Sun is an ellipse, but it is nearly circular, with an eccentricity of about 0.0167. In comparison, the roundness of an ellipse depends on its eccentricity; a perfect circle has an eccentricity of 0. Therefore, if "ellipse 1" has a higher eccentricity than Earth's orbit, it would be less round than Earth's orbit; otherwise, Earth's orbit is rounder.
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.
The Earth's orbit around the Sun is not a perfect circle, but rather an ellipse. This means that the distance between the Earth and the Sun varies throughout the year, with the closest point being perihelion and the farthest point being aphelion. This elliptical orbit is one of the reasons for the changing seasons on Earth.
It is a wavy ellipse. Wavy because of the Moon. The ellipse is close to a circle, but the Earth is just a little closer to the Sun in the Northern Hemisphere's Winter. All orbits are ellipses. The gravitational perturbations caused by the Moon causes VERY TINY ripples in the elliptical path; "wavy ellipse" may be overstating the case.
It is called an ellipse.
Earth orbits the Sun in an ellipse; the Sun is in one of the ellipse's focal points. The ellipse's shape, in this case, is quite close to a circle. The average distance from Earth to Sun is about 150 million kilometers.
Earth's orbit around the sun is best represented by an ellipse with a very small eccentricity, which means it is almost a perfect circle. The eccentricity of Earth's orbit is about 0.0167, making it very close to a circular shape.

The Earth's orbit around the sun is an ellipse, not a perfect circle. This means the distance between the Earth and the sun varies slightly throughout the year, causing the change in seasons. The orbit is slightly elliptical due to gravitational interactions with other celestial bodies and not a perfect circle.
Earth's orbit (revolution) around the Sun is not circular - it's an ellipse. However, this ellipse is fairly close to a circle.
An ellipse.
As the foci of an ellipse move closer together, the ellipse becomes more circular in shape. When the foci coincide, the shape is a circle. Note that circles are a subset of ellipses.

Yes; the circle is a special case of an ellipse.
