Oval or elliptical shaped. (Not a perfect circle)
The extent to which Mars' orbit differs from a perfect circle is called eccentricity. It measures how elongated or stretched out the orbit is compared to a perfect circle.
The eccentricity of an orbit is not measured in days. The excentricity is a numeric value between 0 (for a perfect circle) to 1 (for an extremely prolonged elipse).The eccentricity of an orbit is not measured in days.

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.
Technically, the true shape of the earth's orbit is an ellipse ... a slightly squashed circle. But if you saw the orbit drawn on paper, you couldn't tell it from a perfect circle. It's eccentricity is 0.017, meaning that the longest dimension of the ellipse is only 1.7 percent longer than the shortest dimension. It looks to you like a perfect circle, and you have to do some fine measuring to detect that it's not.
The path Earth travels around the sun is called an orbit. This orbit is elliptical in shape, meaning it is not a perfect circle but is slightly elongated. Earth takes 365.25 days to complete one orbit around the sun.
Nearly a perfect circle, with a radius of 93 million miles.
If by revolution you mean the spin on it's own axis this is more or less a perfect circle. If you are referring to it's orbit around the sun, this is elliptical, not a perfect circle.
Mercury has the most elliptical orbit among the planets in our solar system. Its orbit is significantly elongated, with the eccentricity of 0.2056, which means that it deviates the most from a perfect circle compared to other planets.
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 elliptical, not a perfect circle. This means that the distance between the Sun and Earth is constantly altering during the orbit of the Earth.
