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.
A revolution: The Earth revolves in an elliptical (oval) orbit around the Sun. This orbit is planetary; the Sun is a star, and a large object that orbits a star is known as a planet.
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 shape of the orbit of each planet is an ellipse. An ellipse is a geometric shape that is like a flattened circle. The Sun is located at one of the foci of the ellipse, not at the center.
Most orbits are elliptical; all NATURAL orbits are. There are two foci, or focuses, to an ellipse. The distance between the foci determines how eccentric, or non-circular, they are. If the two foci are in the same place, then the ellipse becomes a circle. So a circular orbit would have only one focus.
Planets orbit the sun in the shape of an ellipse, which is an elongated circle similar to an oval. When it was first discovered that the Sun is the center of the solar system, it was thought that all the planets had a circular orbit, but the calculations didn't fit.
Earth's orbit (revolution) around the Sun is not circular - it's an ellipse. However, this ellipse is fairly close to a circle.
The orbit of a planet around the sun is called an ellipse.
All orbits are ellipses. You might describe an ellipse as a "flattened circle", but mathematically, a circle is a special version of an ellipse in which both foci are at the same spot.

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
More eccentric.

The orbit of the Earth around the Sun.It's an ellipse. Perhaps that's the answer. Or perhaps a revolution.It takes a year.It lies in the ecliptic.
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.
