All planets actually follow an elliptical orbit.
It is called an ellipse.
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 orbital path is technically an ellipse with the Sun at one focus. The eccentricity of the ellipse is 1/60 which is quite small. A good approximation for the orbit is to consider it as a simple circle but with the Sun at a distance of 2.5 million km away from the centre. So the Earth's distance varies from 147.1 to 152.1 millon km with a mean value of 149.6 million km. The Earth is closest in the first week in January.
The orbit of the Moon around the Earth is elliptical. An ellipse is a flattened circle, much like an oval. The Moon takes just under a month to revolve around the Earth. Looking down on the Earth above the North Pole, the Moon revolves counterclockwise around the Earth, which is the same direction that the Earth rotates on its axis.An ellipse. Very close to a circle though.Unlike many other moons, the Earth's moon follows an elliptical orbit.
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.
The Earth's orbit is close to being a circle. So, the ellipse is one with a small "eccentricity".
It is 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.
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.
An ellipse.
Earth's orbit (revolution) around the Sun is not circular - it's an ellipse. However, this ellipse is fairly close to a circle.
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.

An oval. Or an ellipse.
ellipse is the shape of an egg
Yes; the circle is a special case of an ellipse.
